How Does Windows & Doors Work in Cambridge, MA?
We follow a proven step-by-step process to deliver outstanding window & door installation results for every Cambridge 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.
