Window & Door Installation
in Waltham, MA
Professional window and door installation services across Massachusetts. Alfa Construction replaces drafty windows and worn-out doors with energy-efficient, secure, beautifully crafted alternatives that transform your home's comfort and appearance.
Professional Windows & Doors for Waltham Homeowners
Replacing windows and doors in a Waltham historic home requires a contractor who understands the difference between a quick swap and a proper installation. Alfa Construction takes the time to evaluate every opening, address any hidden damage in the frames, and install units that match the proportions, grid patterns, and hardware styles of the original — because in Waltham, the details define the home.
The beautiful old windows in your Waltham home may have historical significance, but they are costing you a fortune in energy loss. Single-pane glass, warped sashes, and crumbling putty allow conditioned air to escape constantly. Many Waltham homeowners layer storm windows, plastic film, and heavy curtains just to stay comfortable, but these are band-aids, not solutions.
For Waltham homes where preservation guidelines restrict full window replacement, we offer high-performance storm window solutions and weatherstripping upgrades that significantly improve energy efficiency while keeping original windows intact. We work within whatever constraints your Waltham property requires.
Windows & Doors Note for Waltham
Waltham's older multi-family buildings often have a mix of original and previously replaced windows in varying conditions, and whole-building window replacement projects create a uniform appearance and maximum energy savings.
Alfa Construction has the experience and sensitivity to handle window and door replacement in Waltham's most treasured homes. We do the job right, we respect your property, and we deliver results you will enjoy for decades. Reach out today to get started.

Our Windows & Doors Process in Waltham
We follow a proven step-by-step process to deliver outstanding window & door installation results for every Waltham homeowner.
Free In-Home Consultation
We visit your home, measure every window and door opening, assess the condition of existing frames and sills, discuss your performance and aesthetic priorities, and present options that fit your goals and budget. You receive a detailed written estimate with no pressure and no hidden costs.
Product Selection & Ordering
Based on your preferences, we help you choose from our range of trusted manufacturers. We guide you through frame materials (vinyl, fiberglass, wood, composite), glass options (double-pane, triple-pane, Low-E, argon), hardware styles, and colors. Every unit is custom ordered to your exact measurements.
Careful Removal & Opening Prep
On installation day, we carefully remove old windows or doors, protecting your interior from debris. We inspect the rough opening for rot, water damage, or structural issues and make any necessary repairs. Proper flashing and waterproofing membranes are applied to prevent future moisture problems.
Precision Installation
Each window or door is shimmed, leveled, and plumbed in its opening for a perfect fit. We insulate the gap between the unit and the framing with low-expansion spray foam, install interior and exterior trim, and caulk every joint. The unit is tested for smooth operation and airtight seal before we move to the next one.
Final Testing & Walkthrough
We open, close, lock, and unlock every window and door, checking for smooth operation and proper seal. We verify that hardware functions correctly, screens fit securely, and trim is clean and finished. We walk through the results with you, answer any questions, and leave your home spotless.
