My side wall had me worried for couple of years as the condition is deteriorating! I've looked for few contractors for helps but to no avail due to the difficulty of accessing to the wall. Finally, CWP help to solve my problems with their specialty!
Maruf and Jahid were very professional in assessing the issue and wasted no time in resolving it efficiently and effectively. They also communicated in a polite manner. After work was completed, they thoroughly cleaned the work area and shifted the furniture back carefully. Overall very satisfied with the work done. Highly recommended!
We engaged the company to help us to find the root cause of pipe leakage. The staff was very helpful and quickly arranged Mr Jamshed to come our place to check. We really appreciate his kindness support and will engage the company service again. Mrs Chu from Seletar Estate
