What Professional Window Work Includes

Your home deserves more than a quick swap. As a full-service handyman, McDonnell Construction, LLC handles every step with care so your new windows look great and perform the way they should for years.

• Assessment and sizing to match your home's openings, trim details, and design style
• Material guidance on vinyl, aluminum, fiberglass, or wood-clad frames with the right Low-E glass package
• Structural checks at the sill and framing, including repairs where moisture or insects have weakened wood
• Precision installation with proper shimming, air sealing, flashing, and drip edge integration
• Interior trim, drywall repairs, and paint blending so the update looks original to your home
• Cleanup and haul-away of old units with a tidy job site at the end of each day

Permit needs vary by municipality and window type. We coordinate requirements and keep your project on schedule.

Why New Windows Pay Off

Old windows leak air, let in noise, and can invite moisture problems. Replacing them improves comfort right away and often increases resale value. With modern glazing and tight seals, your HVAC system runs less, which can help reduce monthly utility costs. Curb appeal also gets a lift thanks to clean sightlines and fresh trim. We install and replace windows across Northeast Florida with craftsmanship you can count on.

Because every home is unique, we tailor options to your goals. Want a bigger kitchen view? We can widen an opening and frame a new header. Need easier operation for a hard-to-reach space? Casements or awning units might be the better fit. Prefer a classic look? Grids and wood-clad profiles keep the style authentic without giving up energy performance.

How Our Process Works

Clear steps keep your project smooth and stress-free.

1. Conversation and vision check: We start with your wish list, photos, and any concerns like drafts or fogging.
2. Measure and plan: Exact sizing, scope, and an itemized proposal with timeline targets.
3. Selections: Frame material, color, hardware, and glass options that fit your budget and style.
4. Preparation: Permitting as required, order confirmation, and scheduling that respects your routine.
5. Installation: Careful protection of floors and furnishings, precise fitment, and weatherproofing.
6. Wrap-up: Punch list, warranty info, and tips to keep everything operating smoothly.

Care tips we share during install help you get more life from your investment. Keep weep holes clear, vacuum window tracks seasonally, and rinse coastal salt from exterior hardware during dry spells. A little attention goes a long way toward smooth operation and tight seals.

Window Replacement and Installation

Whether you're updating one room or the entire home, we match product performance to your priorities. Noise on a busy street calls for laminated glass. Strong afternoon sun suggests a lower solar heat gain number. For high-wind exposure, we recommend frames with sturdy corner keys and reinforced sash, plus glass packages that meet the performance ratings your property needs.

Our team coordinates related trades when the scope is bigger than a simple swap. That can include minor framing, drywall repair, trim carpentry, and paint. If a larger opening or transom is planned, we'll handle structural support, electrical repositioning, and exterior finishes so everything ties together cleanly.

Projects and Situations We Handle

Homes in our area range from cozy bungalows to modern builds. Each comes with different needs. We frequently replace leaky single-pane units, upgrade builder-grade sliders, and install impact-rated glass for storm resilience. When rot or termite damage is uncovered, we repair sills and studs before setting the new frames so you don't trap a hidden problem behind fresh trim.

If you're remodeling, windows often anchor the design. A larger picture window can open up a family room. A bay or bow can add seating and light in a breakfast nook. For kitchens, casements over the sink improve reach and airflow. Bedrooms may benefit from quieter glazing and easier egress options.

• Whole-home window replacement with coordinated trim and paint
• Impact-rated units for storm resistance and security
• Custom sizes for additions and wall modifications
• Conversions from single-hung to double-hung or casement for better ventilation
• Patio and pocket slider upgrades for larger openings to outdoor living areas
• Moisture, rot, or insect-damage repair at sills and jambs before installation

Built for Our Climate

Our coastal climate brings bright sun, humidity, and frequent afternoon storms. That combination can challenge seals and finishes. We recommend frames and glass packages that resist corrosion, reduce heat gain, and stand up to wind-driven rain. Proper sill pan flashing and head flashing matter just as much as the window itself, so we detail these layers carefully to prevent leaks and drafts as temperatures swing.

During summer, interior humidity can collect on cold glass. Choosing the right Low-E coating and ensuring balanced indoor ventilation helps minimize condensation. Thoughtful placement of operable units also improves airflow, so your home feels comfortable without relying only on the thermostat.
