Nobody wants to get home only to find the basement is full of water and if there is a way you can prevent this then you should take it. 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. Basements which have not been made to resist water leakage are susceptible to mold growth and the people living in the house will be at risk a far as their health is concerned and this is not a situation you want to put your family through. Do not make a hiring decision before getting referees from the contractor who can tell you about the kind of an outcome they got from working with the contractor. You will not be doing your bank account any justice when you are spending money on a contractor you are not sure can do the job to the standards you are expecting. 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.
Experience might seem like an obvious thing but it makes a whole difference on whether a job will be just good or great. Do not think of it as a disrespect because it is this information that gives you an idea of the task you should assign. Do not just think in terms of years when you are inquiring about the experience level. 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. If the contractor is willing to break the law in his work, you should know that he or she is not a trustworthy person and this is not someone you should be inviting into your house. The services should come with a warranty because it is an assurance that you will not be throwing away your money only to have the same kind of a problem a few months later. 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.
