"We were extremely happy with the work performed by H&M. Moises, Hector and crew were courteous and did whatever needed to please us. They did most of the renovation in our condo......painting, installation of bathroom cabinets, sink, installed tile floor, etc. They also installed vinyl flooring in our kitchen, living and dining rooms. They had a plumber replace our heating baseboard, I would highly recommend H&M if you want excellent work done!!"

Even though people may think it is expensive, this is a very luxurious type of item and I do think they provide a great value for your money!"

"Gus and his crew were professional and accurate. They installed siding on our large colonial house which was in need of many exterior repairs, They made the house like new. Gus stayed in the budget. The place was left clean after each day of work. The entire job took less than 4 days. Gus provided everything needed and went above and beyond to make sure everything was repaired, sealed and finished with great detail. Several of our neighbors commented on the efficiency of the workers and on the beautiful finished exterior. We plan to use Gus for all our future projects because he is is knowledgeable of construction and has access to different craftsman he employs for all aspects of home renovation."

FAQs for sunroom or patio enclosure building service projects in East Northport, NY

A sunroom is a fully enclosed space with walls of windows or glass. It allows you to enjoy the outdoors from the comfort of the indoors, protected from bugs and weather. It functions as an additional room in your home. A covered patio extends your home's roof over an outdoor area, providing shade and shelter while remaining open to the fresh air. It's a great way to enjoy outdoor living while being protected from sun and rain.

Adding screens to your porch is the most budget-friendly way to enclose it. Screening keeps out insects and debris while letting you enjoy the breeze and outdoor ambiance. It's less expensive than installing full walls or glass enclosures and doesn't usually require permits, making it an efficient way to upgrade your porch.

If you're transforming your porch into a fully enclosed living space like a sunroom, you'll likely need a sturdy foundation, such as a reinforced concrete slab, to support the structure. For a simple screened-in porch, you might be able to use the existing floor and support posts without additional foundation work. It's best to consult a professional to determine what's needed for your project.

An enclosed porch can be considered a living space if it's fully enclosed with solid walls and windows, has a proper roof, and includes heating and cooling systems. It should also have direct access from inside your home. When these criteria are met, the space becomes an extension of your home's livable area.
