It’s been a good 18 months since I last posted a review in which time Hennessey’s have carried out more work for me. These include repointing brickwork, replacing rotten sills, repositioning guttering, repairing a roof valley, repointing rear and front patios, replacing fence panels in our back garden, replacing an old wooden fence and posts with concrete posts and wood panels in our front garden and lastly repairing our garage flat roof with new boards and felt. A lot of work but all carried out professionally and at a good price. In these days of cowboy traders Hennessey’s stand out as one of the good guys !

I had a number of quotes and Hennessy's was professionally and was also fair. The work carried out was of good quality and their workmen both proficient, helpful and professional. They communicated what they were going to do and when and did exactly what they said they would do. The work was completed on schedule and on budget. They were tidy workmen clearing up as they went. I would not hesitate to use them again and would recommend them.

Excellent company. We had a new kitchen extension built by Hennessy’s. Work was finished to a very high standard. Completed to schedule and budget. Brendan and his team kept us informed at all times and were always very friendly and helpful. I would have no hesitation of recommending Hennessy’s to anyone. I plan to use this company again for future work

We contracted Hennessy Builders for carrying out remedial structural work and renovation on an newly bough Victorian house. Quoted prices were fair, both for initial work and subsequent extras. Work was thorough and timely. Communication was excellent throughout the work. Team members on-site were always thoughtful, attentive and helpful. Quality was excellent. There were almost no snags, and the very few that arose were always promptly resolved. Above all, I felt we could trust Brendan and his team to fix our problems and realize our vision effectively and at a fair cost.

Excellent work was carried out by Hennessy on completion of a single-story extension. I found the team to be very polite, tidy, kind and easy to get on with. I am very happy with the work done on my property, it was a difficult job due to the previous builder who left me with a lot of unfinished and incorrect work which needed to be rectified, Hennessy agreed to take over the work and have done an excellent job on my property, they are honest, fair and very helpful in decision making, I will use them again. I highly recommend Hennessy for any home projects.

We have used Hennessys previously for a number of jobs, mainly large ones like having all the pebbledash removed and the house re-rendered. So when it came to having a new kitchen fitted and floor laid in the conservatory Hennessys was our first port of call. As previously the work was carried out in a highly professional manner and we were kept advised of proceedings at all times. There were some unforeseen problems (it is a 1930s house) but these were sorted without any fuss. The Tradesmen were professional, courteous and friendly and really knew their stuff. Mr Hennessy and his supervisors kept us updated daily. It is so nice to know that Hennessys, my local builder, still gives that personal touch and undertakes work of the highest calibre and at a fair price. Companies like this are hard to come by.

A leak in our bathroom needed repair and some floor boards replacing . Hennessey came promptly, provided a fully itemised estimate which was kept to and explained time job would take. Work involved installing a new toilet and also rebuilding parts of the units. All was completed to schedule and to a high standard. We were kept informed of progress throughout. Friendly and observed Covid precautions. A good experience an would use again.

I’ve used Hennessey’s before and had no hesitation to use them again when further works were required to my mother’s house. This time it was reinforcing a plastic corrugated roof which had sagged and replacing mastic and grout in a shower surround which was leaking. Also replacing carpet in the bathroom with a non-slip surface. The work was carried out quickly and efficiently to a high standard yet again. Many thanks to Geoff, Anthony and Kevin for a job well done.

In the strong winds in March chunks of mortar came loose from ridge tiles which in view of the age and condition of all the ridges and hips mean relaying all of them. In addition, a flat asphalt roof needed replacing. Hennessey’s provided a good priced quote and carried out the work to a high standard. Having had work done by them before I was confident they would do a good job and I wasn’t disappointed.
