Sergio and the crew at 4Nalski Construction replaced the original exterior trim on my 90 year old house with PVC. This included matching the molding crown and other unique details. They did an excellent job, in a timely manner and at a reasonable price. I won't hesitate to use them in the future and recommend them highly.

Siding & Exterior Trim on Cape Cod, done the Fornalski way

On Cape Cod, the outside of a house is a working system, not a decoration. Salt air, wind-driven rain and winter storms find every shortcut, so we do not take any: proper flashing, straight courses, tight corners and trim details that shed water instead of trapping it.
We install and repair cedar shingle siding, replace rotted trim with long-lasting PVC that keeps the original profiles, and handle the gutters, doors and small exterior repairs that come with the territory. Whether it is one weathered wall or the whole envelope, the house ends up looking right and staying dry.
Salt air, nor'easters and horizontal rain are hard on a house, and they are merciless on shortcuts. We flash and layer every detail the way coastal work demands, then finish it with straight courses and tight miters, so your exterior looks sharp in year one and still holds in year fifteen.

What homeowners say about this work
Sergio and his crew removed and replaced the wooden shingles on one side of my house. He responded quickly to my text message and met with me within two days. His quote was sent to me within two days and was very reasonable. The crew arrived the following week. Work was completed within three days and looked great. I had requested end vent with a screen. Sergio had even taken pictures of the vent with screen when I was not available to see vent before placement! Sergio is at the top of my list for future building and repair work!
Work performed by 4Nalski included repairs to exterior of home, shutters installation, installation of garage doors, trim work and painting. Very responsive with all aspects of the job, completed the work efficiently and reasonably. I'm thrilled with the end result!
