How Paver Sealing Has Impacted One Contractor’s Cleaning Business

From the Fall 2011 Issue of Pressure Cleaning Contractor Magazine

Interlocking Concrete Paver Sealing is a growing and profitable add-on service for power washing contractors.14 New

Jon Chapman of Pro Pressure Clean and Seal in Tampa, Florida, started pressure washing part-time in 2003, going full-time by 2005. Initially, Jon focused solely on removing chewing gum, but quickly saw the need for roof cleaning, then deck and dock sealing, and now window cleaning. However, his biggest growth opportunity occurred in 2008 when he discovered the interlocking concrete paver sealing market.

“Florida is a huge market for paver installations, and most installers don’t offer or don’t do a very good job of sealing,” he explains. “There are more docks than decks here in Florida, and since I was doing dock restoration, the paver pool deck was an obvious add on.”

Today, paver sealing makes up as much as 60 percent of Jon’s business. He says a typical job, such as a pool deck with patio, takes around one to two hours to aggressively clean, depending on the amount of problems or neglect. The sealing takes one-half to one hour, “and we’re done. Five to seven hours total with an average ticket of $1000 on a typical pool deck.” And the product line he uses is by Seal ‘N Lock.


Trial and Error

Jon turned to Seal ‘N Lock after several unsuccessful attempts with a number of other products. First, he tried solvent acrylic sealers, but his customers began calling and complaining about “white blush” – i.e., white spots that appeared on the pavers due to trapped moisture under the acrylics.

Solvent-based sealers require that contractors first wash the substrate in order for the sealer to adhere to it. Then they must wait several days for all of the moisture to evaporate from underneath. “It’s very hard to measure whether the moisture is all gone because although it can look dry, there still may be moisture underneath, which causes the pavers to turn white,” explains Russ Heitman, Director of Strategic Development for the Seal ‘N Lock (SNL) System Corporation.

However, the white blush may not show up for a few months. “If it turns white, it’s very difficult and time consuming to fix,” Russ adds. “Now you’ve got a huge problem. For a $2,000 sealing job, you’re putting a $20,000 pool deck at risk.”

That’s why Jon switched from solvent-based products to water-based sealers, but but he wasn’t happy with those either. “They didn’t have much shine and they were way too difficult to apply to make it profitable for me,” he says.

Eventually, one of Jon’s local suppliers invited him to a demo by Rich Colletti of Seal ‘N Lock, “and I was hooked immediately,” he explains. “A one-day sealer. How cool is that? The dollar signs started flashing before my eyes.”

Unlike the other sealers Jon tried, Seal ‘N Lock could be applied to damp surfaces so he did not have to make repeat trips to the client’s property. “One of the miracles of Seal ‘N Lock is that it releases all moisture during the curing process,” explains Russ. “This reduces your waiting time and lets you clean, sand and seal all in one day. With the cost of fuel, who wants to come back?”

Another difference between SNL and other sealers, according to Russ, is that it is a two-coat process – that is, two coats of the same product – and it’s easier to apply than other products. In fact, contractors are encouraged to walk on the product between coatings to ensure the sealer does not pool in low spots, which can cause the pavers to appear darker than in higher areas.

“We want evenness, so we want contractors to walk on it, spread it with a broom, or blow it with a blower, whereas other products don’t allow that,” says Russ. “A lot of the Seal ‘N Lock process is counterintuitive, which is why we strongly encourage contractors to take the Seal ‘N Lock Authorized Technician Course.”

Although the SNL course has a list price of  $249, for 2011 it’s being offered at a greatly reduced price – even free in many instances – and is being offered as part of the PWNA flatwork cleaning certification course in Nashville. (A FREE class is also being offered in Scottsdale, Arizona on September 24 and in Charleston, SC on September 30.

“It is a professional-grade product and therefore we highly recommend that contractors get trained on the product before using it,” says Russ. “By taking the class, you learn tips, tricks and techniques, get registered for leads in your area, and receive ongoing training offerings.” Participants also get a 74-page manual, as well as access to the Seal ‘N Lock team. “We want to walk you through that first job,” stresses Russ.

Additionally, for 2012, SNL will be adding even more value to their contractors’ toolboxes by offering products that not only enhance the paver’s current tint, but can actually recolorize it. “This will add tremendous value to the course and to the contractors’ list of services,” Russ adds.


The Market

Interlocking concrete paver sealing is a growing trend for pressure washing contractors. It’s not only a natural add-on service, it solves the all-too-common problem of ruining sand joints when power washing pavers.

“If you’re not careful when cleaning, you can wash away the sand, which is a structural component of the pavement, which can lead to joint failure,” according to Russ.  By sealing with SNL after cleaning, contractors actually lock the joint sand, “which other sealers don’t do. Now pressure washing contractors can wash it, sand it and seal it. At that point it ‘locks’ the joint sand, which makes future cleanings easier. Sealing adds value to their customers by enhancing the pavers’ color and protecting their investment from wear and stains.  The full service ‘clean and seal’ contractor is seen as a true expert.”

Jon said adding paver sealing to his business came fairly easily, as he only approached his current clients at first. Then he added the service to his website and worked hard on his SEO (search engine optimization). “Now I am almost always on the first page of Google in my area,” he adds.

While Jon still offers pressure washing and roof cleaning, he says he can now turn down the small jobs. “It seems like there are billions and billions of pressure washers in Florida and the pricing is ridiculous,” he adds. In a saturated market, paver sealing has given Jon a competitive edge. “Its profitable, and fun.  I like my work, and I’m good at it,” he adds, pointing out the positive customer reviews he’s received on sites such as Angie’s List.

The most time-consuming part, according to Jon, is the sanding that occurs between the washing and sealing steps. “But with Seal ‘N Lock, we can wash sand in, wash off excess and be ready to seal in about another one to two hours.”

To get started in this market, Jon suggests calling some of the bigger paver manufacturers in your area and finding out who the installers are. “Start working the installers and get some SEO on your website for paver sealing.”

Finally, Jon adds that he is happy to give free advice to anyone, but points out that so are the staff of Seal ‘N Lock. “So feel free to call.”
