This is a highly skilled job and if done by a nonprofessional, it can cost you thousands or even a complete brick replacement to fix. Sealing products can be highly flammable you will want a professional using them around your home.
2. Polymeric sand /hard sand. Is a difficult subject to understand so I will try to explain. The majority of company’s say they use polymeric sand, when they don’t. When they try to use it with sealer they create a big mess. Polymeric sand must be installed properly. Our crews are trained by the manufacture how to install it properly. You can use polymeric sand with water base sealers because it is the water that activates the polymeric fibers to set up. Oil or solvent base does not. But the downfall of that is when you back roll the sealer with a roller the sand gets stuck to the roller going all over the brick. Not to mention all the polymeric fibers or Portland cement are stuck to the top of the brick leaving a haze because they never blew it off correctly. Please keep in mind when you use a good water base stabilizer sealer it stabilizes the joint sand which makes it hard, making hard or poly sand unnecessary. Solvent base sealers are going to need the extra step of wetting the sand and letting it dry before sealing it. The only way to properly do it is blow all the old joint sand down at least 1 inch out, and start from scratch.
- If You have to have polymeric sand and want solvent base sealer we will move from a 2 step process to a 3 step process. Which means an extra day for labor and means a bit more money. Normal procedure is to wash and clean one day and come back another day after the brick is dried fully to sand and seal. If you want polymeric sand, you need to come back sand, and wet the polymeric sand, then wait at least one day for that to dry and then seal the following day. This makes it 3 trips to your house instead of 2. Be prepared to pay for this extra step
3. What sealers are they using? Are they solvent based(oil) or water base? Both have pros and cons you should be aware of.
- Oil/solvent base being the strongest last 5-7 years.
- Oil base is much harder to install, but you get a better result. Oil/solvent base is very expensive and difficult to get off.
- Water base last 3 to 5 years.
- Water base can be removed much easier without harsh strippers. And if a mistake is made by a contractor or mother nature (rain) which happens, the water base cannot be fixed as easily as solvent base.

A cheaper price does not mean quality. Landscapers and pressure washing companies will always be cheaper due to unskilled labor and inferior products. But they will never be able to produce a quality job a professional company will. If you don’t want to pay twice or even three times what you paid the first time. Do your due diligence and hire a professional.
