Do not use this service! They are not reliable and do NOT screen their contractors. We spent over $1K to have a shower kit installed. It was done incorrectly and we now have to take it out and fix it. He did not follow instructions that were provided for back wall support and used liquid nails and sheet-rocked over the flange. We have not been able to reach him and we cannot even install our new shower door because he did not square and true the wall. Measurements are 55 inches at bottom and 56 at the top. the name of the contractor is Oliver Construction. I am disappointed that Thumbtack did not screen this unbonded and unlicensed contractor.
