I think the Home Improvement Service Provider has set to use terms of contracts so it does not involve any legal agreement. If you have better home improvement project than you must have to dispose lawyer for the agreement.
You must have to read the terms as per the sign the contract with the company. If it is so vital than you must have to get appoint the attorney to give legal agreement of the said contract.
