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.

Landscaping- 28 Oct 2026
Neli took over our patio project after another builder, who claimed to have over 20 years of experience and excellent five star reviews, left us with very poor workmanship. Neli stepped in and redid the patio to the agreed specifications. The only downside was that the work took a few weeks longer than expected for various reasons. However, the patio has now been completed as agreed, and I’m happy with the final result. I appreciate Neli taking on a job that another builder had left in such a poor state and would recommend him.

Shane has done a great job of laying our new patio. He removed the old one, then laid the new one ensuring an even fall over the whole area on various directions to ensure runoff to the drainage areas. We have had several heavy rains since with no puddling. Shane built a concrete slab for our hot tub again perfectly level no puddling from the rain. Also inserted a drain for hot tub emptying. The patio has two separate areas, which he bordered with black blocks, which has helped to set it off nicely. Picket fence and matching gate, and new entrance gates with quality fixings look great too.

Fencing- 13 Oct 2020
We had a new fence and part of the front garden concreted and the other part slabbed. Everything was done to a excellent standard and even when the weather was bad they still kept working hard. I would definitely recommend worx constructions as they where by far the best quote and they turned up on time every day and worked neatly and tidy. Thank you for the hard work.

Kitchen Fitting- 18 Oct 2022
If you need someone amazing to help install your kitchen, Przemek is the perfect guy for the job. He is absolutely brilliant at what he does, very precise, very communicative and super friendly. Not only did he do my kitchen, he also did extra things for me for which he didn’t take extra money. There were a couple of things that were wrong with the original kitchen design that was made for us, but Przemek picked up on these quickly and managed to tackle them really effectively and quickly. Another amazing thing is that if you choose Przemek, you won’t need to get a plumber or an electrician as Przemek does all of it, and he does it extremely well. I very very highly recommend Przemek for everyone.

Plastering- 4 Sep 2020
Living room walls and ceiling plastered. Communication leading up to the job and during was great. Richard was great to deal with. Started first day and arrived early which is always a good sign. I went away for a few days whilst work being done and Richard kept me informed and sent through pictures and video. Really, really pleased with finish and can’t wait for it to dry out now. Cleaned up once finished too. Richard to come back to finish off once other works done and this hasn’t been a problem with him either. Would definitely recommend.

Extensions- 15 Aug 2013
Father and son team, Pip and Jake Palmer, are the bee's knees! You'd be hard put to come across a pair of more hardworking, experienced, conscientious, resourceful, reliable, skilled and meticulous builders. Nothing was too much trouble and no problem insoluble. Watching Pip and Jake work on the superb garden room extension which they've built us, it soon became very obvious that they love what they do and that they take a real pride in their job. Truly a pair of proper 'old school' builders! Five stars out of five!' Mr and Mrs Cox Nottinghamshire
