About Our Window Work

Residential Window Installation in Massachusetts

A window is only as good as the opening it sits in. Square framing, proper flashing, correct shimming and sealed nail fins all decide whether a Massachusetts window keeps water and cold out for twenty years or two.

MZR Construction Inc opens the wall, checks the framing, installs the window plumb and level, flashes it to spec and closes the wall inside and out. Interior trim, exterior trim and drywall repair are part of the job, not add ons.

Square and Plumb

Openings shimmed to true square and plumb before the window goes in the hole.

Full Flashing Detail

Sill pan, nail fin tape, jamb flashing and head flashing all installed to manufacturer spec.

Interior Finish Included

Interior trim, drywall patch and paint touch up handled by the same crew, no subcontracting.

Manufacturer Warranty

Andersen, Marvin and Pella installed per spec so the material warranty stays valid.

Windows That Stay Tight

The difference between a window that lasts twenty years and one that leaks in five is not the window. It is the flashing detail and the shim work behind the trim.

FAQ

Window Questions

Depends on the frame condition. If the existing frame is square, dry and structurally sound, an insert replacement saves money and time. If there is any rot, racking or moisture damage, a full frame replacement is the honest answer.
Most window replacements average one window per hour once the crew is on site. A whole house of ten to fifteen windows is a two to three day job. Full frame replacements or repair work extend that. You get a schedule with the estimate.
Yes. Once the old window is out, we walk the sill and jambs, replace anything soft or rotted, then install the new window into sound wood. Setting a new window into rotted framing is the fastest way to void the warranty.
Window brand, size, glass package, trim complexity and the number of openings all move the price. Nobody can quote a whole house honestly over the phone. We measure, then put the number in writing so you can compare bids.
We install windows across Massachusetts. Give us your town and ZIP code when you call and we'll tell you right away whether your house is in our route. That call is free.
Yes, at (617) 952 3986 any hour. When a broken window or storm damage opens the envelope, we can board up and secure the opening. Permanent replacement gets quoted once the house is closed in.
Yes. When storm damage breaks windows, we inspect, photograph and write a scope your insurance company can review. You file the claim. We provide the documentation your adjuster requests.
