Windows & Doors in Greater Boston, done the Vanguard way

Isometric illustration of windows & doors work on a Greater Boston home

A great window installed poorly performs like a bad window. That's why Vanguard Construction Group treats the installation as the product. We square and shim every unit, flash and seal every opening, insulate the gaps and finish the trim inside and out so it looks like the window was always there.

We replace anything from a single failed unit to every window in the house, plus entry doors, storm doors and sliding or French patio doors.

Older North Shore homes are full of original single pane windows that leak heat all winter. We've replaced them in every style of home from Lynn to Wakefield, keeping the character and losing the draft.

What's included

  • Energy efficient replacement windows
  • New construction windows for additions and remodels
  • Entry doors and storm doors
  • Sliding and French patio doors
  • Rot repair around openings before installation
  • Air sealing and insulation at every opening
  • Interior and exterior trim and casing

Fellipe and his team did an outstanding job painting our house! They worked incredibly hard, spending long hours every day with smiles on their faces, even in the hot weather. Their craftsmanship and attention to detail were exceptional.
Fellipe went above and beyond by suggesting that we paint the doors, something I hadn't even thought of. He also painted our front door, even though it wasn't included in the contract. The team repaired all of the rotted window frames beautifully, fixed and replaced the steps, garage door. They also cleaned up thoroughly at the end of each day, and completed the entire project in a very short time.
Our house looks absolutely beautiful, and we couldn't be happier with the results. Fellipe and his team are true professionals and wonderful people. We are so grateful for their hard work and highly recommend them to anyone looking for a reliable, honest, and talented painting company!

Common questions

Will new windows really lower my energy bills?
Replacing old single pane or failed units with modern double pane windows makes a real difference in drafts and heat loss. The exact savings depend on your home, but the comfort difference is immediate.
Do I have to replace every window at once?
No. Many homeowners replace the worst units first and phase in the rest. We'll help you figure out which openings are costing you the most.
Can windows be installed in winter?
Yes. We replace windows one opening at a time, so your home is never left exposed. Each unit is out and sealed back in within the same visit.
