Windows & Doors in Flower Mound, TX

Window and door work in Flower Mound means working on large brick homes built between 1995 and 2008, many of which are now hitting the 20-30 year mark where builder-grade vinyl windows fail all at once. The black clay soil underneath most of the town adds a second pressure: foundation movement racks door frames and opens gaps around window rough openings. Whether you need a single casement window replaced or impact glass on a two-story great room, call (509) 265-6387 for a written price before any work starts.

Why Flower Mound Homes Are Different

Flower Mound grew fast, and the housing stock shows it. Planned communities like Wellington, Bridlewood, and Stone Hill Farms went up quickly during the 1990s and 2000s with builder-grade vinyl windows that had a 20-30 year service life. That window is closing right now, and homeowners across Flower Mound are replacing windows in clusters rather than one at a time.

The soil underneath makes every installation trickier than it looks. Expansive black clay swells and shrinks with rainfall, which means door frames shift and window rough openings rack slightly out of square. A window installed without proper shimming and anchoring will bind within a few seasons. We take frame readings on every opening and record them in the measured survey we hand you before quoting.

HOA covenants add a procedural layer most contractors miss. Many Flower Mound neighborhoods specify approved exterior colors, frame finishes, and grid patterns. We pull the HOA design guidelines before ordering product, because a non-conforming unit you cannot install is the most expensive mistake in this trade.

Our Main Flower Mound Services

Two services account for most of the calls we get from Flower Mound homeowners: full door installations and full window replacements. Each has its own page with local pricing and conditions.

Door Installation in Flower Mound

Door installation in Flower Mound usually means pulling a rotted or racked door frame out of a brick opening and rebuilding the rough opening square. The clay soil here puts constant pressure on door frames, and south-facing exposures near Lake Lewisville see humidity cycling that accelerates wood deterioration. We measure the existing opening, check the frame for racking, and specify the replacement before any work starts. The full breakdown lives on our Door Installation in Flower Mound page.

Door Installation in Flower Mound

Window Replacement in Flower Mound

Window replacement across Flower Mound is dominated by homes built in the late 1990s and early 2000s that still carry original vinyl units with failed seals and fogged glass. The work usually involves high window counts, arched accent units, and brick-veneer openings that hide water damage until the OSB sheathing behind the frame is exposed. We quote from a measured survey you keep. The full local breakdown is on our Window Replacement in Flower Mound page.

Window Installation in Flower Mound

Modern window installation with sleek black frame overlooking a landscaped garden
Window Installation in Flower Mound

Window installation in Flower Mound means working on homes built during the 1995-2008 boom, when builder-grade vinyl went in fast and is now coming out faster. The clay soil underneath Flower Mound shifts constantly, which means window openings are rarely square, and correct shimming is the difference between a window that operates for 20 years and one that binds in two. We start every job with a measured survey we hand you before quoting, and the price in that survey is the price on the final invoice. See the full breakdown on our Window Installation hub page.

Single & Double Hung Windows

Signs you need it

Sashes that stick, rattle in the wind, or no longer stay open signal a worn balance system or poor installation.

What it costs in Flower Mound

Replacing builder-grade double hung windows runs $550-$1,100 per opening, with single hung units at $500-$900.

How we do it

We remove the existing sashes, inspect the rough opening for moisture and racking, shim the new frame square, and seal it with backer rod and sealant before installing new sashes and trim.

Horizontal Roller Windows

Signs you need it

Rollers that grind, tracks that fill with debris, and panes that fog between the glass are typical failure signs.

What it costs in Flower Mound

Expect $450-$950 per opening depending on width and whether the track and frame need full replacement.

How we do it

We remove the old sash, adjust the frame to square with shims, install a new track and sash with new rollers, and test the slide before sealing the perimeter.

Casement Windows

Signs you need it

Hand cranks that strip, hinges that sag, and air leaks around the sash edges are reliable indicators.

What it costs in Flower Mound

Casement replacements run $650-$1,250 per window, with wider swings and two-tone frames pushing the upper end.

How we do it

We pull the old crank and sash, address any frame rot or water staining at the sill, install the new casement with a square frame, and check the seal with a smoke pen before calling it done.

Awning & Hopper Windows

Signs you need it

Awnings that leak at the top hinge or hoppers with broken pivots usually need full unit replacement rather than part swaps.

What it costs in Flower Mound

Plan on $400-$850 per opening, with concrete or brick surrounds adding cutting time and labor.

How we do it

We measure the opening from the exterior, remove the old frame, install the new unit with proper drip cap and slope, and seal all four sides with manufacturer-specified flashing.

What Window Installation Costs in Flower Mound

Item Typical range in Flower Mound
Single hung window replacement $500 - $900
Double hung window replacement $550 - $1,100
Casement window replacement $650 - $1,250

How long does full window installation take in Flower Mound?

Most single-story homes with 8-12 windows are done in 2-4 working days. Two-story homes with arched units and brick veneer can add 2-3 days. Call (509) 265-6387 for a written schedule with your quote.

Will the price change once work starts in Flower Mound?

No. The measured survey we take before quoting is the document the final invoice is built from. If we find hidden rot, we show you the photo record and write a change order before proceeding.

Impact Windows & Doors in Flower Mound

Modern floor-to-ceiling panoramic glass windows in a luxury living room
Impact Windows & Doors in Flower Mound

Impact windows and doors in Flower Mound are less about hurricanes and more about hail. The region’s frequent large-hail events turn ordinary insulated glass into insurance claims, and homeowners are increasingly upgrading to impact-rated glazing as an insurance-driven decision. Lake Lewisville proximity adds humidity cycling that degrades seals faster on west and south exposures. Read more on our Impact Windows & Doors hub page.

Impact-Resistant Windows

Signs you need it

Recent hailstorms, cracked or starred glass, or an insurance adjuster noting non-impact glazing on a Flower Mound home are the main triggers.

What it costs in Flower Mound

Impact-resistant window replacements run $850-$1,700 per opening for standard sizes, with larger picture windows exceeding that.

How we do it

We pull the old unit, verify the rough opening is square and structurally sound, install the impact-rated frame and glass with hurricane-specified anchors, and seal with manufacturer-approved flashing.

Hurricane Impact Windows

Signs you need it

Building-code updates, an insurance premium reduction offer, or HOA-mandated upgrades for street-facing glazing are common drivers.

What it costs in Flower Mound

Expect $900-$1,900 per opening depending on the design pressure rating and laminate thickness.

How we do it

We specify the design pressure rating each opening requires, order the correct PGT or CGI unit for that opening, and install it with code-compliant anchoring so the glass and frame work together.

What Impact Windows & Doors Costs in Flower Mound

Item Typical range in Flower Mound
Impact-resistant window replacement $850 - $1,700
Hurricane impact window $900 - $1,900
Impact sliding glass door $2,500 - $5,800

Are impact windows worth the cost in Flower Mound?

Yes, primarily because hail claims are frequent and insurance carriers often discount premiums for impact-rated glazing. The payback period on premium reduction alone typically runs 5-8 years. Call (509) 265-6387 for a written price with your exact specifications.

Do impact windows change the look of a Flower Mound home?

Not with modern laminated glass. Impact-rated windows from PGT and CGI are available in the same frame colors and grid patterns that Flower Mound HOAs already approve. We pull HOA guidelines before ordering.

Energy-Efficient Windows in Flower Mound

Modern residential home exterior with sleek black frame windows and doors
Energy-Efficient Windows in Flower Mound

Energy-efficient windows in Flower Mound fight two fronts: summers above 100°F that drive cooling bills, and winter ice storms that can push below 10°F and stress every seal in the house. Homes built before 2008 typically have single-pane or early double-pane units with U-factors that now look obsolete. The full product breakdown is on our Energy-Efficient Windows hub page.

Low-E & Argon Gas Glass

Signs you need it

Rooms that stay hot in summer despite A/C, fading on furniture near south-facing windows, or condensation between panes.

What it costs in Flower Mound

Low-E argon-filled replacements run $650-$1,300 per opening, with triple-pane pushing the top of that range.

How we do it

We spec the correct Low-E coating for each exposure, order units with argon fill, and install with continuous foam sealant to keep the gas inside the glass, not the gap.

ENERGY STAR Replacement Windows

Signs you need it

Utility bills that spike in July and January, drafty frames, and glass that feels warm to the touch on summer afternoons.

What it costs in Flower Mound

ENERGY STAR labeled units run $600-$1,250 per window installed, depending on frame material and glazing package.

How we do it

We check the U-factor and SHGC ratings for each window against the DFW climate zone, order the correct CWS or ECO Window Systems unit, and install with a complete perimeter seal.

What Energy-Efficient Windows Costs in Flower Mound

Item Typical range in Flower Mound
Low-E argon-filled replacement $650 - $1,300
ENERGY STAR replacement window $600 - $1,250
UV-blocking laminated glass $700 - $1,400

Which energy rating matters most in Flower Mound?

SHGC matters more than U-factor here because summers dominate the load calculation. A low SHGC cuts solar heat gain in July, which drives most of the energy savings. Call (509) 265-6387 for an opening-by-opening rating plan.

Will new windows lower my Flower Mound utility bill

Most homeowners see a 10-20% reduction in cooling costs after replacing 1990s-era builder windows with modern Low-E units. The exact number depends on window count, exposure, and current insulation.

Sliding & Patio Doors in Flower Mound

Modern glass door with professional metal handle installation
Sliding & Patio Doors in Flower Mound

Sliding and patio doors in Flower Mound sit at the intersection of two local problems: clay soil racking that pulls frames out of square, and humidity from Lake Lewisville that swells wood and corrodes rollers. Most patio doors in Wellington, Bridlewood, and Stone Hill Farms are original to the home and overdue for replacement. See the full scope on our Sliding & Patio Doors hub page.

Patio Doors

Signs you need it

A door that sticks halfway, a frame visibly out of square, or daylight visible around the slab edge means the frame has racked.

What it costs in Flower Mound

Standard patio door replacement runs $1,500-$3,200, with wider openings and transoms pushing higher.

How we do it

We pull the old door, check the slab for settling, rebuild the rough opening square with shims, and install the new door with a continuous sill pan.

Impact Sliding Glass Doors

Signs you need it

Hail storm damage, an insurance recommendation, or a desire for storm-rated glazing on a rear elevation facing open greenbelt.

What it costs in Flower Mound

Impact-rated sliding glass doors run $2,500-$5,800 in Flower Mound depending on panel count and glass type.

How we do it

We order the correct impact-rated unit from PGT or CGI, prepare the opening with strapping for uplift resistance, and install with the manufacturer’s anchoring schedule.

What Sliding & Patio Doors Costs in Flower Mound

Item Typical range in Flower Mound
Standard patio door replacement $1,500 - $3,200
Impact sliding glass door $2,500 - $5,800
Screen door installation $150 - $400

Why did my patio door suddenly stick in Flower Mound?

Clay soil movement under the slab is the usual culprit. Foundation shifts rack the door frame, and the slab will not re-level itself. Call (509) 265-6387 for a frame measurement and written replacement quote.

Can you replace just the sliding panel and not the whole frame in Flower Mound?

Sometimes, if the frame is still square and the track is intact. We measure the racking first. Most Flower Mound patio doors we see are too far out of square for a panel-only swap.

Impact Garage Doors in Flower Mound

Modern black pivot door installation in a minimalist concrete luxury home.
Impact Garage Doors in Flower Mound

Impact garage doors in Flower Mound address the same hail exposure that drives window upgrades, compounded by the fact that most garage doors face the street and take the full force of a storm. Homes built in the 1995-2008 wave came with standard steel doors that dent, bow, and fail under hail. Full details are on our Impact Garage Doors hub page.

Hurricane-Rated Garage Doors

Signs you need it

Visible dents from hail, doors that no longer seal at the header, or insurance pressure to upgrade to wind-rated construction.

What it costs in Flower Mound

Hurricane-rated garage doors run $2,800-$6,500 installed in Flower Mound, depending on width and reinforcement.

How we do it

We remove the old door and tracks, reinforce the opening with wind-rated brackets, and install the new door with a continuous bottom seal and storm-rated track system.

Energy-Efficient Garage Doors

Signs you need it

A garage that stays hot enough to heat the rooms above it, or a door with single-layer steel and no insulation value.

What it costs in Flower Mound

Insulated energy-efficient garage doors run $1,800-$4,200 in Flower Mound, with polyurethane cores at the upper end.

How we do it

We spec the correct R-value for the door given the garage’s exposure, order the insulated unit, and install with new weatherseals on all four sides.

What Impact Garage Doors Costs in Flower Mound

Item Typical range in Flower Mound
Hurricane-rated garage door $2,800 - $6,500
Energy-efficient garage door $1,800 - $4,200
Garage door replacement (standard) $1,200 - $2,800

Is an impact garage door required by code in Flower Mound?

Not uniformly, but wind-load requirements are tightening and some insurance carriers now require impact-rated garage doors on new policies. Call (509) 265-6387 to review your specific street-facing opening.

How long does a garage door replacement take in Flower Mound?

Most single-door replacements are done in one day. Larger two-door setups with custom trim add a second day. The measured survey gives you a written schedule with your quote.

Custom & Geometric Windows in Flower Mound

Modern steel-framed French doors opening onto a sunlit courtyard with trees
Custom & Geometric Windows in Flower Mound

Custom and geometric windows in Flower Mound are not optional aesthetics; they are structural features of the housing stock. Planned communities like Wellington and Bridlewood are full of arched, palladian, and radius accent windows over entryways and great rooms, and those units are now failing right alongside the rectangular ones. Read the full scope on our Custom & Geometric Windows hub page.

Geometric & Shaped Windows

Signs you need it

Fogged glass inside a trapezoid, hexagon, or radius window, or a frame that has twisted out of shape from clay soil movement.

What it costs in Flower Mound

Geometric replacements run $900-$2,800 per unit depending on shape complexity and whether a custom template is required.

How we do it

We take a precise digital template of the opening, order the unit from a manufacturer approved for custom glazing, and install with structural silicone and the correct flashing for the surrounding brick.

Arched & Curved Windows

Signs you need it

Condensation trapped in the arc, visible seal failure at the curved edge, or a frame that has pulled away from the brick.

What it costs in Flower Mound

Arched window replacements run $1,100-$3,200 in Flower Mound, with radius-top units at the upper end.

How we do it

We template the arch with a physical pattern, order the curved unit, and install it with a custom drip cap and brick-mold returns matched to the home’s existing trim.

What Custom & Geometric Windows Costs in Flower Mound

Item Typical range in Flower Mound
Geometric shaped window replacement $900 - $2,800
Arched window replacement $1,100 - $3,200
Oversized custom opening $1,500 - $4,500

How long does a custom window take in Flower Mound?

Custom shapes take 4-8 weeks from template to install, because the unit is fabricated to your specific opening, not pulled from stock. Call (509) 265-6387 for a written timeline with your template.

What if my HOA does not approve a custom window?

We pull the HOA design guidelines before ordering any custom unit. If the covenant specifies a particular grid pattern or frame color, we spec the unit to match and submit the approval package for you.

Some windows also have rotted OSB sheathing behind the frame, which needs repair before the new unit goes in. Every price we give is written, with no change orders unless we show you the photo evidence first.
