"Kurt was easy to reach via email or telephone. Apprised us of his approach to stripping our deck of its horrible paint coating and was upfront of the general cost during his first visit. He did need to be reminded to provide a specific contract upfront. Otherwise, deck restoration work progressed quickly once weather conditions permitted start and Kurt finished the large project within a few days."

"I highly recommend Deck Buddy. Our screened porch (inside and out), deck and stairs were badly in need of cleaning and resealing. We had 4 different companies out here to quote the job. Deck Buddy was by *far* the most professional of the bunch, extremely competent and moreover pleasant to work with. They came exactly on time and were able to answer all my questions and were extremely knowledgeable about the work and the products/services they would use/perform. Their bid was neither the highest nor the lowest. Their service tech spent 3 days here cleaning, repairing, and refinishing our porch and deck. It looks like new. I am so pleased. We have attempted to do this work ourselves in the past, and paid to have it done by a different company once before, but never achieved the results Deck Buddy did. I should add, that when we paid to have this work done before, it did not seem like the other company applied very much product to the wood. This time, with Deck Buddy, you can see the wood is thoroughly sealed. Also, in comparison to our earlier experience, Deck Buddy took care to cover all my plants and also the house siding to protect from overspray. (Not protecting my plants was a problem with a different powerwashing company we hired once - my hostas were shredded - you have to watch out for this). Deck Buddy was extremely careful with everything and left no mess or debris behind, the porch and deck look great, the garden is unscathed. It was a job well done. Thank you!!!!"

"I called C & Painting immediately to see if they could put the basement back together, and they came within 2 days and work tirelessly replacing drywall, baseboard, and then painting the damaged areas of the basement. C Painting was extremely accommodating, given my Insurance Company did not approve the claim for all of the many damages to my home. The bill was reasonable at $2400, given the amount of work, materials, and need for exact precise measurement when filling in the walls with new drywalls and paint--making the room look totally brand new. Oh, I must also say that what I LOVE about this company, is that they clean up days and hours of mess extremely well. C Painting is ABSOLUTELY the BEST in the Washington DC Metropolitan area. Thanks for this opportunity to praise this professionally and exceptionally organized company. M Valerie Mills"

"It went ok. Workers were professional and pleasant when performing work. Not always on time as scheduled. Deck maintenance was high quality. Other exterior work appears to be good. Exterior pressuring washing was well done. Expensive."

Customers say: Terrific value

"Vtile did an amazing job replacing the brackets on my deck that were rusty and old. It was a small project but important to me that my deck remained safe for me and my guests. The price was reasonable, they showed up on time, did an excellent job and left the work area spotless! Iâ m a very happy customer!"

Deck Cleaning FAQs, answered by experts

Most building codes require that spindles or balusters on deck and stair railings be spaced no more than four inches apart. This safety standard, often called the '4-inch sphere rule,' is designed to prevent small children or pets from slipping through the railing. A good way to visualize this is that a 4-inch sphere should not be able to pass between two spindles. For the same safety reason, the space between the bottom rail and the deck floor should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is crucial to check your local building codes to ensure compliance before starting your project.

Pressure-treated decks last 15 to 20 years on average, but with proper maintenance, you could get 40 to 50 years of value from yours. Reseal your deck every one to two years, and replace old or rotted wood as soon as possible to avoid structural damage. Where you live plays a role in the lifespan of your deck. Intense sunlight, rainfall, wind, and hail can reduce the deck’s lifespan.

In most cases, there should be a small gap between the house and the deck, usually no more than ½ to ¾ of an inch. This space allows water and moisture to flow through instead of pooling against the side of your house. It also lets flashing protect your siding from runoff, which is one of the most common issues with decks.

Both a well-constructed deck and a patio can add value to your home. Patios are generally cheaper to build but don’t offer the same aesthetics as a quality deck. Therefore, decks can be more appealing to buyers than patios, increasing a home's resale value.

It’s best to prime composite decking before painting. This promotes better paint adhesion, helps create a smooth finish, and can mean the paint job will last longer. Always follow the manufacturer’s instructions for application, allow ample primer drying time before painting (typically 24 to 48 hours), and thoroughly clean the deck boards to promote the best adhesion.
