Used them for a single storey extension and then again for another one. the owner kept us updated every day with what was happening next. Dealt with building control for us so we did not have to. Cheers.

Was a bit nervous about the garage conversion to be honest. You can tell they actually care. Faultless.

Mostly good. Communication could have been better in the middle bit!

Used Brennan & Sons Builders for a driveway last month. Turned up when they said they would. Finished the driveway on time and on budget, which everyone told us never happens. Proper old fashioned service. Faultless.

The garage conversion looks great. Price crept up a bit from the quote though.

Decent, a couple of things were missed first time round but they came back to sort it. Might have been unlucky.

Great garden wall, great price. Cheaper than the big names by miles.

Been meaning to write this for a while. Dealt with building control for us so we did not have to. Would use again.

cant fault them. Quality of the brickwork is superb, neighbours keep asking who did it. Thanks the project manager!

Nobody answers the phone. Left messages, no call back. Terrible for a building company

Hi Tracy, apologies. This should not have happened and we have changed how enquiries are handled so it does not happen again.

Rang up on Wednesday morning about a driveway. Quote was detailed, no surprises on the final bill of £52,750. Polite, hard working and turned up every single day. Cant recommend them enough.

Roof leaked within a month of the loft conversion. Would not come back to look at it. Had to pay someone else.

Emailed three times and rang twice about the garage conversion. Not one reply. Gave up and went elsewhere.

Started the single storey extension then disappeared for three weeks to another job. Left us with no kitchen.

Hi Shannon, we are really sorry about the wait and for not keeping you informed. That is not how we normally work. Please get in touch and we will make it right.

Quality of the brickwork is superb, neighbours keep asking who did it. Everything was explained properly without any jargon. Even sorted a small extra thing for free. Recommend to anyone.

Dealt with building control for us so we did not have to. Finished the double storey extension on time and on budget, which everyone told us never happens. Price was £2,200 which was less than I had been quoted elsewhere. Job done.

Used Brennan & Sons Builders for a garage conversion last month. Quote was detailed, no surprises on the final bill of £63,600. Communication was spot on the whole way through. Told everyone at work about them.
