"Franklin Trojan did an excellent job for us removing all the old concrete pointing from our house front and repointing with proper lime mortar. It took them slightly longer than expected as the concrete had to be cut out with power tools in places but the end result looks great and they stuck to their original quote. They also did a great job repairing flashings to a chimney and repainted all the front windows to finish off. We got 3 quotes, all about the same, but Franklin Trojan was recommended after other local work in Willesden Green. Happy to recommend."

"They were experienced, agreed to visit to look at the work before providing a quote. they provided all the materials, and the works was done in quick time. They were very professional, clean and I would recommend them for this type of work."

"They listened and provided sensible and creative solutions to fix various problems left by the previous builder. Their work was finished to a good standard (as good as the pictures in their instagram account) and are clean and tidy. They are busy so might not be able to come on certain days but this is not an issue for us. We worked around each other. I will be getting them back again later this year to do other work."
