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.

I was renovating a flat that needed a lot of TLC and Danny and Thomas did an incredible job. I gutted the bathroom, had plumbing and electrical work completed throughout the property and asked Thomas to do a few bits of carpentry. Danny went above and beyond to answer any questions I had and he offered practical advice/solutions to any problems we encountered during the build. Thomas was friendly and his workmanship was stupendous. He always arrived on time and worked tirelessly to get the job done within the given time frame. I'm really happy they came and worked on my flat because they were both lovely. I'd recommend Hennessy in a heartbeat.

Bathroom, replastering and redecoration

Very pleased that I opted for Hennessy Ltd to do quite a lot of work in my house. This included installing a shower to replace the bath as well as updating my small bathroom. Other work included replastering the stairs and hallways and redecorating various areas in the house. Thomas impressed me as he looked for solutions to various problems eg the incompatible drainage systems for the bath and shower. Danny was very patient and reassuring throughout the month the men were here – especially as the bathroom is a very small area to deal with and I wanted as large a shower as possible! I am very happy with the final result.

Chimney Breast

We were so lucky to choose Hennessy for the building work on our chimney breast. We had the best experience and everyone was so professional and helpful from the very first phone call. We had our brickwork and fireplace removed plus surrounding shelves and then plastered and painted. Even though we held them up waiting for our flooring to be laid so they could fit the skirting boards, they were so patient and kept in contact with courtesy calls and emails. They were prompt and tidy and the work was excellent. We're so pleased and wouldn't hesitate to use Hennessy again for any work we need in the future.
