"About 8 years ago Darren replaced a badly installed flat roof on my Orangery. Two days ago I experienced a leak... He sent Bradley who spent around 2 hours examining and then carrying out a repair which I'm confident will work. Darren phoned me to say that there wouldn't be any charge as his work is guaranteed 25 years. What a lovely change to find a proper building company."
"Fantastic service. We had a leak to our flat roof attached to our extension... Darren and Bradley at Smartseal provided me with enough confidence to proceed with them. They explained their work and Bradley did a really thorough job which they've guaranteed for 25 years. Really happy, highly recommended."
"Darren and his crew came to my rescue after the last storm... Darren organised scaffolding fitted the same day and covered the damaged flat roof! The end result looks amazing, a fantastic product! I cannot praise this company high enough, they were professional from start to finish. Without a doubt I would highly recommend them."
"Very happy to have found Darren and Bradley who saved us from a leaking flat roof. Darren was very responsive and helpful through the quote process as our job was not straightforward. He helped organise scaffolding and Bradley did a brilliant job on the roof. Photos provided throughout to show us progress. Definitely recommend them."
