    Like most good builders, the majority of our work is generated through word of mouth. This is important to us, because we believe it demonstrates consistent client satisfaction. But don’t just take our word for it, here’s what our customers think…

    "Bobby and his team recently put wooden floor down in my sitting room, dining room, and hallway. The quality of the flooring and workmanship was top notch. They cleaned up at the end of each working day and kept disruption to a minimum. We also had extra electrical sockets fitted and they made good any plastering where needed. All in all I found Bobby and his team to be polite, cheerful, reliable and honest. His quote was very reasonable and I would not hesitate to recommend him to anyone."
    Mrs Dorothea Francis
    "I desperately need a new bathroom, but being 90, I was somewhat nervous about the disruption. My son-in-law recommended Bobby. It was a big relief to have such friendly and considerate people working in the house. What's more they did a fantastic job! I couldn't be happier."
    Betty - Morden
    "Bobby and his team converted half our garage into an office. They have done an exceptional job and we are extremely pleased with the work done. They have great attention to detail and we would recommend them to family and friends. We will definitely use BuildOn again in the near future. They are extremely polite, happy and very nice people to have around and were tidy after each day. Thanks guys !!!"
