Do extension builders near me need insurance?

While it isn’t a legal requirement, most builders carry public liability insurance to cover accidental damage or injury during work. Always ask to see proof of insurance before agreeing to a project.

Do local extension builders offer guarantees on their work?

Yes, many local home extension builders in your area should provide a guarantee covering their workmanship for a set period, often lasting several months to a few years depending on the project size. Always check what the guarantee covers before work begins.

What should I ask before hiring an extension builder?

Ask about previous work, project timelines, cost estimates, and payment terms. It’s also wise to discuss materials, planning permissions, and how any unforeseen issues will be handled. You can easily view examples of previous projects of extension builders near you on MyBuilder.

How much deposit should I pay for an extension project?

Deposits usually range from 10% to 20% of the total cost. Make sure the payment schedule, scope of work, and conditions are clearly written into a contract before the extension project starts.

Extensions- 22 May 2019
Jacob was very accommodating and flexible. His team were great and he completed the work nicely. There was some splatter from the cementing on to my neighbour's wall. He tried to clean it off but it wouldn't all come off. Therefore, he went out and bought some paint and repainted their wall. I would get him back for more work without hesitation. When looking for a builder - they have to be honest, work hard and to an excellent quality without cutting corners. They should be responsible to ensure neighbours property isn't damaged and provide consultancy as what we want and want is realistic can differ significantly! - and if any issues rectify them once the job is complete and of course provide good after sales. I have used several builders over the years - very few tick all of the above boxes. Jacob certainly does.

Repointing- 28 Oct 2015
Great job thank you. Dan provided a full and comprehensive quote (which was the cheapest) and as soon as we awarded to him he arranged for the rubble in our garden to be removed the next day. He took us through all the options and completed everything to a high standard within a week. We are very happy with the service and will use DRConstruction again for any future building work we need

Restoration & Refurbishment- 23 Feb 2024
Adams workmanship was great - we had a full ensuite shower room installed with all walls needing erecting, plumbing, electrics, tiling and install work. Adam undertook either the work or the organisation of other relevant trades to make sure the job was complete to a high standard. He kept us informed throughout the process with regular updates and made sure we were all in agreement before any changes were made. This also meant that the final price came in with no surprises. I would definitely recommend Adam to anyone looking for a bathroom install or similar work.

Restoration & Refurbishment- 2 Oct 2024
I just wanna express honest with you I met up with Mr John on two occasions and I told him everything I want confirmed we confirmed the price he sent us a spreadsheet but later on confirmed a figure once that was done he said send pictures. I’ll get the items for you and will get everything done for you in a time which was originally 2weeks . Then 2 month and half later he ignore my calls very unprofessional and has outstanding task he left and still not even correct , I am not able to go in to all the details but I tell you for free how I’ve been treated for the last few weeks mentally draining and for example he said let’s get his electrician because he needs the person doing the work side-by-side and if I’m honest, they’ve done nonsense because the media where the plug is is not correctly positioned in fact, the TV does not go in properly as they positioned it in the wrong place they didn’t check where the TV was meant to go initially I have to sort this out myself.

Extensions- 10 Jul 2019
The initial reason we chose Hatch Construction to start is down to Lee.......... Text missing Cleanliness – Not only I have commented, but each of my neighbours who are all elderly were very complimentary about how the team worked and how clean the site was. I was very happy that my patio and garden were all left intact. Staff – A great team, knowledgeable, friendly and flipping hard workers. Nothing was ever a chore for them and they were happy to share their knowledge and experience. An overall lovely group of blokes. Quality of Work – The workmanship was spot on, even with a knowledgeable family member at hand to oversee some of the build, he was more than happy with the workmanship demonstrated by the guys. Been in the house a month or so now and all appears to be as it should be. Knowledge of Suppliers – The Company has links to many reputable companies in the area to put you in contact with, we used all that were recommended to us and we couldn’t better the price and service anywhere else without dipping on quality. Flexibility – A very flexible team, whether time constraints or having to work around certain events, Lee will aim to make it as plain sailing as possible, given that having building work is such an upheaval. Overall I would recommend Hatch Construction to anyone, they are an honest firm and will do their best on the job in order to meet your expectations. I am more than happy with my new house and love what they have done to transform it

Groundwork & Foundations- 20 Oct 2016
L & H Building and Groundworks provided a concrete base for a garden office. The price was within budget and when the turned up, they were on time, the equipment they used was professional and clean and Jake was very courteous. The area was kept clean at all times and the front garden and decking was protected throughout the job, so all in all I found them a very professional company to work with and would recommend them to anyone who would require their services.
