Plastering- 14 Sep 2025
I was initially fairly happy with the work David completed, despite the mess usually left at the end of each day (including empty cans and wrappers left on side). However, one room had multiple failures and after David eventually replastered two of them, there were further failures on the other walls as well as one of the re plastered walls. Despite having to repair these large areas of blown plaster myself, David still demanded the £90 half day rate for re plastering the initial failed walls. I expressed that I was not happy with this as well as the constant mess, regular let downs, turning up late and leaving early (including texts at 8.30/9 on the day of work to say he wouldn’t be coming), also the use of my tools and not cleaning them properly afterwards. David simply replied to my concerns, “clearly you have issues mate”. An extremely unprofessional individual, and I would absolutely not recommend!!

Joinery & Cabinet Making- 10 Apr 2019
What a great lad, came over in the evening to do a site visit and came back promptly with a very competitive quote. I had to delay start briefly as I had no labour to help me remove old roof. Liam stepped into the breach and helped me with this. The following week he was there on time and ready to go not phased by slight delay because of weather & unseen snags with levels, sorted by my bricklayer another My Builder member. Liam will work well and safely on his own with a full kit of his own professional tools and his output is tremendous. On the first morning of deck job I had to go out for a while,I returned and was amazed at what he had achieved on his own, we are talking 5mtr 9" x 2" beams lifted up onto a structure and fixed. At all times he worked in a seamless professional manner, with a positive plan for the job, discussing any unforseen snags with an appropriate solution before overcoming them. Liam was always polite and courteous carrying out a marvellous job in record time for me. I have other jobs that I would not hesitate to employ Liam on as soon as he is free I can be fussy with my jobs, my background was Maintenance Manager at a London Uni and I have exacting standards. Liam met all my criteria. Don't be put off by his youthful looks, this is one good tradesman with old school skills and ethos. My long term friend who did the final roof cover, a specialist Flat Roof Contractor for 40 years+ commented on what a good roof he had built.

Bathroom Fitting- 16 Sep 2021
Zach removed an old sink and bathroom floor from my house. The job wasn't straightforward and we had to change plans after discovering problems with some of the fittings and products I'd ordered. He was fine with this and was fair with pricing. I would definitely recommend Zach to renovate your bathroom.

Extensions- 22 Jun 2018
We are 3 weeks in to a 5-6 week build. I really cannot speak highly enough of Owen, Will and Tom. Within 3 days they had created footings, knocked down walls, dismantled our kitchen and had steels in ready for the extension. The speed of progress has continued, the project management has been outstanding, everything delivered on the right day, without lots of materials being stored on site. They have been incredibly polite to our neighbours, ensuring they are parking with consideration and not inconveniencing anyone. I feel incredibly fortunate to have found this team via this site. We look forward to working with Wright and Wrythe on future projects, we wouldn’t go anywhere else.

We employed Nicky to install our kitchen, splashback and worktops. Nicky and his brother Liam were punctual, polite, tidy and most importantly their work was excellent. Having mentioned we were after a media unit in the front room, Nicky suggested they could make something bespoke for us and we trusted them to do it and what a fantastic job they did. We would highly recommend Nicky as the work they have done is nothing short of fantastic!

Questions to ask local loft conversion companies in Sudbury

Choosing the right loft conversion company for your job requires finding someone who understands your home and your goals.

Find out which company can share your vision by asking the following questions:

What experience do you have with loft conversions in Sudbury?

A local loft conversion company in Sudbury will know the types of properties and building styles common in your area, as well as the planning and building regulations that apply. Ask about similar projects they’ve completed locally.

Are you insured, and do you offer a warranty for your work?

Insurance protects your home during the loft conversion process, while a warranty shows the company’s confidence in the quality and durability of their work.

How do you handle planning permission and building regulations?

Established loft conversion companies in Sudbury should understand local planning rules and building regulations. Ask how they’ll manage permissions, inspections, and compliance to avoid delays or legal issues.

What is included in your quote?

Ensure the quote covers all essential aspects of the loft conversion: structural work, windows or skylights, staircases, insulation, labour, and any additional fees. Understanding this upfront prevents unexpected costs later.

Do you manage the project from start to finish?

Some Sudbury loft conversion companies offer full project management, coordinating architects, builders, and tradespeople. Others may only handle part of the conversion. Clarifying this early on helps you understand what support to expect.
