"The weather this summer was challenging with rain and then heat ,but Cully managed to make good time on the project once we were able to begin. He was responsive and did some extra things that he did not need to do per the contract we signed, which was nice.He was very neat and performed a complete cleanup essentially daily. He was respectful of the property and took time to minimize any impact on things like plants, shrubs,etc. Very happy with the service. Very competitive estimate. Uses top quality products, from a local, small business retailer, not big box store paints and stains."

"First of all, I tried to get good pictures to show how well they did, but our house is a deep(ish) red color so maybe it's hard to tell. We had a lot of black something (Mold?) growing on our siding and we wanted it off. It looked bad and my husband said it's bad for the paint so we hired No Grit to pressure wash the house based on a recommendation from a friend. I was thrilled to find out they were available to do this so late in the year; their customer service is excellent! Roy is very friendly and professional; showed up when he said he would, it took right about the amount of time he estimated, then he picked his stuff up, said "Thanks!", and left. LOVE the outcome! All the black stuff is gone! Our home looks so CLEAN Thank you!"

"Overall it went pretty well.  They stared early and stayed late to make up time lost for rain.  They were very concientious about picking up every day.  John and his entire crew were very friendly and respectful. 

At first I wasn't very pleased with the number of visible seams in the flashing on the roof facing the driveway.  The roof is very "wavy" due to the settling of our ancient house and apparently the seams were unavoidable.  Everything has settled more and it is fine.  What is most important is that John talked to us about it and wanted to do anything he could to make sure we were happy with the job.

We would hire him again for work.  He seems to love what he does and he wants to make sure his customers are happy and it shows."

Sandblasting Services questions, answered by experts

Soda-blasting systems are slightly more expensive than sandblasting systems. To soda blast, you’ll need to spend a few hundred dollars for a blast hose and nozzle, a compressed air supply, a blast generator, a moisture decontamination system, and sodium bicarbonate media, a recurring cost because the powder is not reusable. To start with sandblasting, you will need to spend upwards of $30 for a blast pot, a blast gun, an air compressor, and sandblasting media, many of which are recyclable—further reducing the cost. The total cost for either will depend on the size of the system.

The best way to sand a deck is by cleaning it, sanding the boards and stairs with 60- or 80-grit sandpaper, and sanding the railings and posts with 80-grit sandpaper. You should sand in the direction of the wood grain to avoid damaging the timber. When sanding your deck, use medium pressure and aim for an even sand. Pressing too hard with a sander can damage decks, as most are softwoods.

Sanding and pressure washing serve different purposes in deck maintenance, so one is not necessarily better than the other. Pressure washing is ideal for annual cleaning to remove dirt, grime, mold, and mildew. Sanding is a deeper restoration method used to smooth rough surfaces, remove an old finish, and prepare the wood for a new coat of stain or paint. The ideal process for refinishing a deck is to first clean it (with a power washer), then sand it, and finally apply the new stain or finish. While cleaning should be done annually, sanding and staining are typically needed only every one to three years.

DIY is possible, but professional services ensure even removal, safety compliance, and proper cleanup.

Sandblasting refers to the process of cleaning a surface using compressed air and aggregate. Soda blasting is the gentlest type of this method, but it differs from sandblasting that uses mineral or other aggregate, since sodium bicarbonate breaks apart more easily than other forms of blast media and, therefore, cannot be reused.
