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.

We had our Kitchen refurbished after water damage from the bathroom above. The team at Hennesseys worked with us listening to all our concerns. Everything was done to a great standard and the finish is 1st class. A special thanks to Dean and Colin who went the extra mile to ensure perfection. Tradespeople like this are hard to find. I would definitely use Hennesseys again.

We had a damp wall that looked as if it was caused by one piece of leaking guttering and over time had eroded away brick pointing. Hennessey’s were quick to attend and quoted to fix the guttering and repoint the whole wall. In view of the cold weather at the start of the year the work was completed in stages when the weather permitted. It wasn’t a big job but Dan at Hennessey’s kept updating us when work could continue and be completed. All in all it was a job well done. Good communication, good price, good workmanship.

We've held off writing this review for a few months to ensure things are still up to scratch after moving back in. I am happy to say that our home is perfect! Dean, Brendan and the teams at Hennessy were absolutely fantastic, even considering everything came to a halt due to the first lockdown. We were always kept fully up to date and the teams made sure we could access the site at any time to check on the work. This was a very large and scary project for us but from the start, we were so glad we chose Hennessy for this build. 100% recommend them and happy to be a reference as well.

Hennessy replaced incoming water main, completed structural repairs, painting and decorating. Easy to work with. Clear pricing. On time and efficient at work. Good quality finishes. My tenants were happy to have them in the house and Hennessy were courteous to them at all time. Will use them again for future work.
