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. With the right basement proofing techniques, the space will be free from moisture leakage which can cause a mold situation leaving your household exposed to fungal infections. 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. As far as your house and your finances are concerned, you should not be spending money on any professional unless you are sure the job output you will get from them is something you can live with. Let the contractor tell you why he or she thinks the job is the right fit for him. The response should demonstrate that the person is better than the other candidates.
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. Contrary to what many people believe, the experience is not just about the years the person has been in the industry. It also means getting an idea of the basements the contractor has worked on and how many of them have been in a good shape ever since. A person might have been in the field for long but have just a few projects on his back.
A license is necessary before you give the contractor the job. It is illegal to offer the services without a valid license and someone who is willing to break the law cannot be trusted. Ensure the services come with a guarantee of warranty because you will not have to pay more for the same if things do not work out after a couple of months. The basement contractor should discuss the techniques he or she used in the project with you before moving ahead with the plans.
