"Moises and Edward and the crew did a repair of my facia. They told me to get PVC so it would last longer. They also repaired cracked walls and ceiling and painted. They did perfect work. Did so good I kept finding more work for them because it looked so good. They are so polite and respectful and right on time. Also they are very fair with their prices and don't push for or more work. I now consider them friends. Don't waste you're time because you won't beat their prices. They can do anything too. Bathroom, kitchen, floors. I will hire them again they are the best."

"I not only had one of their sunrooms installed, I actually have two, which have become my two favorite things in my home! I am so happy with their workmanship, their great communication skills, I just love the product. They took care of any issues immediately. I highly recommend them to anyone. 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!"

"We are completely delighted. Everything went perfectly. Danny, our sales representative, was great at explaining options, and was always available for questions. The expert installers, Andreas and Dmitri, were fun to work with, responsive to our requests, and even installed our new doorbell. I look forward to working with this excellent company again for new windows."

"The boards on the porch of our house were rotting and needed to be
replaced, during the quoting process we decided on the materials to use we wanted Ipe boards (Expensive at $6.25 per linear foot ... but we felt well worth the price) Trust Builders LLC gave us the best quote of all received ranging between $13,000
to $22,000.  They came to our house after getting all of the necessary permits and arranging a trash skip.  Jim the foreman and master carpenter modeled supports for the roof that was sagging, removed the columns and boarding. 
The framing and footings under the porch were then inspected and found to be unsuitable for use.  Further funding was
required for the new footings and framing, these were added to the original quote of $13,000 and came to around $2000 (cost price for materials).
The porch was completed to spec and within budget within two weeks.
We are thrilled with the new porch and are probably going to hire Trust Builders LLC to build out our attic space."
We take great care wit the simplest details.

"Steve was excellent to work with.  We met with Steve's company and two other companies for estimates.  We were most impressed with Steve.  He was very personable and realistic.  He wasn't a salesman with smoke and mirrors.  We hired him and were glad we did. He did everything from going to the stores with my wife to get the right materials, to having a key to our house until the work was done.  Every day I saw progress, he had good communication, and we are very pleased with the end result."

"See above.  Other than being misled by the offer, ie-not realizing that the reason for the appraisal was to obtain a mortgage only, I have no way to rate this service.  Please note, we did not use this service and have nothing negative or positive to say about this company.  Angie's List ought to have an Overall Rating for NA, like they do for the specifics.

FAQs for sunroom or patio enclosure building service projects in Brookhaven, 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.
