"My experience with them was really superb. The owner is terrific he came out personally and explained the products, came out a couple of times when the workers were here. The workers were great, in fact I have some cards for them, where I may have posted them later. They did an excellent concrete work. So they both, did a concrete extension and then they put up the overhead enclosure with a ceiling fan. So anyway we were really pleased, very good customer service, very good attentiveness with a good pricing, I felt very good about the whole thing."

"I just hired this company, haven't started the project yet, but for those whom came to give an estimation i was truly disappointed! Raul, came here took the time to check areas looking for soft spots in the floor, gave suggestions and solutions, and best and worst case scenarios. He had great ideals, gave me options and made me feel secure in knowing what his was doing and what and how they would proceed! That in itself speaks volumes! Others on here whom came were lazy, not looking or have a clue what kind of work was needed, yet spit out an estimate that made me laugh!! I will out of kindness not reveal their name! I will give more reviews as the project gets underway and done. I'll also post before and after photos!"

"In June of 2010 my house flooded due to a faulty toilet tank intake line.  Forever Wood Construction was there within 2 hours & begin the steps needed to start the repair of my home.  They helped me move all my belongings out of the way so they could remove the water damaged part of the walls & the damaged flooring.  They set up blowers & dehumidifiers throughout my house to dry it out so they could proceed to put it all back together.  They totally matched the texture on my walls & you can't tell that I've ever had a flood or had any portions of the walls redone!  They even fixed some long standing electrical issues for me.  Great company!  I definitely recommend this company to others."

FAQs for sunroom or patio enclosure building service projects in Greenwood, CA

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.
