Disappointing Experience The initial response was quick, but the job description and photos weren't thoroughly reviewed. Although the job was completed, the leak returned within days. Despite attempts, there's been no response to finish the job. We'll now have to pay another company, meaning our initial payment was wasted.

An excellent job at a competitive price. Aaron provided a quote which outlined details of the job to be done. They arrived as promised at 7.45 and had the job done in just over 6 hours. The work was neat and tidy and they cleaned up thoroughly after - no mess left for us. Aaron discussed in detail the problems discovered and has suggested further minor work to improve ventilation in the roof - which we will have done. Overall we are very happy with the work and would use Solid Roofing Services again.

They were also able to give advise on the best way to finish off the top of the wall. Secondly, they used the right mix of cement and lime to continue with the same colour mortar. They were also able to calculate exactly the quantity of bricks, cement etc. I would need so therefore there was very little wastage. I would definitely use them again.
