"Todd, the sales rep for patio enclosures was very polite and not a pushy rep. He gave us pictures of what our enclosure would look like on the computer. We liked what he suggested for our space and therefore we bought the sunroom . I would highly recommend Todd at patio enclosure to do give you an estimate of your dream patio enclosure."

Customers say: True professional

"Their work was excellent. He gave me a discount because of health condition. His workers did far more work than I expected. But the supervisor was not going to charge any more than the original estimate. The yard was covered with last year's leaves. When they finished there was not a single leaf left on the ground. They were by far the best Lawn crew i have ever had!"

"I had unexpected excavation of sewage lines in my front and back yards, leaving my driveway, front walk and back patio in shambles with numerous broken flagstones. Loftus helped me revamp the layout and finish some very natural looking hardscaping including flagstone, pea gravel, tumbled edging and a beautiful, functional firepit . Ben's communication was great with reasonable pricing considering the expansive size of the project. I would 100% recommend!"

"I chose The Window Gang for gutter cleaning because of their reviews, and now I know why everyone praises this business. Not only did their man blow the maple seeds off of the roof and screens, he lifted some screens and blew debris out of the whole system. He also inspected them and said they were in good shape. He then cleaned up the area. I highly recommend this company!"

Patios questions, answered by experts

Yes, but ensuring the deck has a solid foundation with adequate footings is critical before building, as the weight of a sunroom will put significant pressure on the structure below. Even if your deck is properly constructed, it may not be able to handle the extra weight. While some basic, lightweight, prefabricated sunrooms can sit on a deck with a strong existing foundation without additional supports, in many cases, the foundation and joists will need reinforcement. It is always best to have a structural engineer perform an inspection to evaluate the deck's quality and structural integrity. A professional can help you decide if reinforcement is sufficient or if it's better to tear down the deck and start over.

The average cost to enclose a patio to create a sunroom is around $5,000, and prices generally range from $3,000 up to $10,000. The price you pay will depend on the state of your patio and whether it needs repairs or additional structural support, the quality of the materials you choose, the size of your patio, and whether you plan to run utilities into and finish the sunroom. The price for a fully finished patio enclosure could run up to around $20,000, while you might pay just $2,500 for a screened-in porch.

If you’re trying to decide between a sunroom and a screened-in porch, the right choice will depend on your priorities. A screened-in porch costs only a fraction of the price of a sunroom, but in exchange, it has much more limited use. A sunroom will add more value to your home, but at a much higher up-front cost and longer construction timeline.

The cost to screen in a porch depends on whether you are adding screens to an existing structure or building a new one from scratch. Adding screens to an existing porch costs about $5 to $7 per square foot, with a national average cost of around $2,800. For example, screening a 12-by-12-foot (144-square-foot) porch would likely cost between $700 and $1,000. If you are building a new screened-in porch, the cost is substantially higher. A new 12-by-12-foot screened-in porch can cost between $6,400 and $18,300, while a new 14-by-16-foot one averages around $11,000. The final price will vary based on the size of the porch, labor costs, and the materials you choose.

Sustainable materials and energy-efficient designs support greener construction options.
