When it comes to water in the house, it is only great if it stays in the pipes until you open them and when there is a problem especially with heavy rains or burst pipes, a flooded basement is a high possibility which is why you should take measures to prevent this before it finally happens. Using some clothes or boards to secure the basement door is not going to be of much help which is why you should get a contractor to do the job. When you have done basement waterproofing well, moisture leakage problems will be avoided and they are not fun given that they are the reason why mold grows which can compromise the health of your family members. A contractor who has done the type of work before should provide you with references you can use to ascertain that you will not be disappointed with the work the person will do. Throwing your money at someone who has not done anything to prove that he or she is able to deliver the standard of work you want is not wise. Ask the contractors you are interviewing what they will give to make your time worthwhile. If the response does not convince you that the person will do an outstanding job, look for someone else.
You should expect great things from a person who is experienced in basement waterproofing compared to someone who has just handled a few projects. It is not disrespectful to ask about this because you will be able to know how much responsibility you should give the contractor. Do not just think in terms of years when you are inquiring about the experience level. You need to know the number of projects the person has handled and how the end result was. Even people who have been doing the work for 5 years might not have the number of projects someone who has been working as a basement contractor for 2 years has to his name.
A license is necessary before you give the contractor the job. The law is very clear about licensure of the basement contractors and if you find someone who is willing to work without going through the proper system to get a license, you should think twice before allowing them to your house. When you are paying for these services, you want your basement to be in order for a long time and you cannot be sure that this will be the case unless you ask for a warranty document of a guarantee from the person in question. There should be a full disclosure of the techniques that will be used during the project before it even commences so that you can know what you should expect.
