Professional Windows & Doors for Marlborough Homeowners
If you have lived in your Marlborough home for more than 15 years, chances are your windows and doors are due for an upgrade. Seals fail, hardware wears, and the energy performance of older units cannot match what is available today. Alfa Construction serves Marlborough with professional replacement services that modernize your home's comfort, efficiency, and curb appeal.
In Marlborough, sliding patio doors are common — and commonly problematic. Tracks clog with debris, rollers wear out, seals deteriorate, and the door becomes an ongoing source of frustration, drafts, and even leaks. Many homeowners avoid using their patio door altogether, which defeats the purpose of having one.
Alfa Construction simplifies window replacement for Marlborough homeowners. We handle everything from product selection to permitting to installation to trim work. You choose your windows, we do the rest — efficiently, cleanly, and with minimal disruption to your family's routine. Most homes are completed in two to three days.

Our Windows & Doors Process in Marlborough
We follow a proven step-by-step process to deliver outstanding window & door installation results for every Marlborough 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.
