Extensions- 7 Apr 2025
Quotes were provided and the job was agreed upon. The project involved a full house restructuring and extension build. However, after several stages of work, communication with Jas was lost, and his co-worker took the lead on site. Several issues arose, such as recommending smart plumbing equipment for purchase, but their plumbers were unable to install it. The tiling, skirtings, and tiles were not completed. Tiles around the columns were cracked. After Jas's team abandoned the project, another plumber had to install all the remaining items. The job was left unfinished, and we had to find alternative contractors to complete it. Significant time and money were wasted due to persistent communication problems, failure to issue invoices, and numerous other issues. Eventually, Jas and his main labourer stopped responding and disappeared, ignoring phone calls and WhatsApp messages. Be aware of these potential issues.

Carpets & Lino- 13 Sep 2026
Couldn’t recommend this guy enough! He was incredibly helpful, professional and went above and beyond to help us when we were in a bit of a difficult situation. He genuinely saved us from what could have been a massive issue and we’re so grateful for his help. Really friendly, knowledgeable and clearly takes pride in his work. It’s rare to come across someone who cares that much about helping their customers. Would 100% recommend and will definitely be using him again in the future. Thanks again!

Carpentry- 13 Aug 2026
Alex did what I asked and did a great job installing the awning. He also installed a metal shed and put up a beam to cover part of a wall. Overall, the work was good, although a few small details were missed in the shed, which seemed to be due to a lack of attention to detail. I found the price a little expensive, but overall I’m happy

Restoration & Refurbishment- 8 Jan 2026
I’m extremely happy with the work carried out by Arindo @ Altd Carpentry. From start to finish, the refurbishment was handled in a very professional and organised manner. The work was completed on time, exactly as agreed, and the quality of workmanship throughout the house is excellent. Everything from the kitchen installation, flooring, tiling, carpentry, electrics and painting was done to a high standard, with great attention to detail. Communication was clear throughout the project, and any questions or small changes were dealt with promptly and without fuss. The site was kept tidy, Arindo was respectful, and it’s clear he and the team take real pride in their work.

Architecture- 5 May 2018
Contracted to provide options for a new garage office and storage solution. They turned up promptly and were very polite and professional. Through many discussions they ultimately offered up a very good bespoke solution for our situation and once planning is approved we will have no issue with looking to them to complete the actual build. We have had a lot of issues in the past finding reliable trades but with ArhiTERRA design and build we felt confident in their ability to both visualise and implement the build as well as follow through on their promises. I would say that for anyone considering discussing a project with them that it is worth your time to at least have a meeting with them and judge for yourself.

Plastering- 26 Jun 2016
We hired Manu and his team to plaster our summerhouse, relocate two radiators and fit a new bulkhead ceiling in the lounge and install LED tape. He was knowledgable, professional and considerate and I highly recommend Manu and his team. Not only did he understand the project for the bulkhead, but he came up with another suggestion which we went with, and friends and family agree looks amazing. The finish on the plasterwork is perfect and Manu and his team worked hard and even left the summerhouse cleaner than when they started! It is great to work with a team who pay such attention to detail, listen to the client and get the job done to a high standard. It was a risk to go with Manu as he didn't have any feedback when I hired him. I actually got him to quote so I could compare prices with someone else I had in mind to do the job, but when I met Manu I felt he would be the better person to do the job as he listened and understood exactly what I wanted and so I ended up hiring him instead. I wouldn't hesitate to hire him for any future jobs. Thank you Manu and team!

What qualifications and experience do you have as an extension builder in Welling?

An extension builder in Welling should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Welling extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Welling?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Welling extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Welling extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
