Here is the main reason you shouldn't go with the cheapest contractor. This home in Avila had Travertine installed around the pool deck. After a beautiful installation, the owner hired a sealing company to seal it. With out knowing the intricacies of sealing travertine, they made a mess. With in a month, the sealer was peeling away.
We came in upon the referral of a friend, striped the sealer off and sealed it right using the same sealer! Many companies advertise paver sealing services, but check references first. Many really don't know what they are doing and it can cost 3 times what they charged to have someone fix their mistakes.
