"Hernan was a pleasure to deal with. He was reliable and efficient. He did general deck cleanup, power wash, and bulky junk removal. He promised the deck would look like new—and it did. I highly recommend."

"Nelson, came to my home last night to power wash my back porch, which has composite decking on it. Nelson went above and beyond, very personable, very thorough, the cost was good and I am so pleased. I would recommend this man in a heartbeat. Nelson was his first name and he is a beacon Falls resident and I know who will be power washing from now on at my house. Thank you so so much."

"I have now had 4 pickups from this company. Each time it has been with different items: I have had my kitchen remodeled,  a deck torn down and rebuilt, a new roof put on, old fencing disc arded, and a yard cleanup. The only difference in pricing was for the roofing and even though ti was more money it was STILL CHEAPER than a dumpster!!! I don't know how these guys do it, but they pickup on time, without issue andfor the cost quoted. I have turned each of my contractors onto them - now they are using them. SO MUCH cheaper and better service than any dumpster company I have used!"

Deck Maintenance FAQs, answered by experts

For a 12x20-foot (240-square-foot) deck, you can expect to pay between $7,200 and $14,400. This cost is based on a general price of $30 to $60 per square foot. The final price will depend on factors such as the decking material, design complexity, deck type, location, and local labor costs. Keep in mind that add-ons will increase the total; for example, adding an under-deck drainage system to a deck of this size could cost an additional $7,700.

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.

Your deck may look or feel fuzzy after pressure washing because the high-pressure spray tears some wood fibers as it removes the outer layer of dead and discolored wood. This fuzzy effect is a normal part of the pressure-washing process and will go away on its own in a few weeks. You can opt to spot-sand your deck if you’d like to remove it more quickly.

Yes, it is possible to build a small, basic deck for $5,000, particularly if you use less expensive materials and a simple design. To stay within this budget, consider a size under 10x12 feet and use affordable materials like pressure-treated wood or cedar. While the general cost for deck building ranges from $4,350 to $12,560, with an average around $8,200, some projects can be completed for as little as $4,350. You can also save on labor costs by doing the work yourself, but be aware that mistakes could end up costing more than hiring a professional. A contractor may have a higher upfront cost, but they can ensure a safe, stable deck that will last.

As with patios, there are many types of deck choices to choose from to add personalization to your home. Some common deck options include:

  • Attached decks are anchored to the home and include simple ground-level options or multi-level structures with stairways and separate landings. 

  • Detached island decks are not attached to the home; they’re a freestanding structure in the yard. 

  • Wraparound decks connect the back of the house with at least one other side and often are built with railings for safety. 

  • Multi-level decks connect your deck through varying levels of elevation, featuring landings that are attached to stairs.
