Extensions- 6 Jan 2023
I am doing a double storey L shaped extension and the experience has been great so far. Vascontractors have been open, transparent, clear in communication. Have always understood the customer need. The quality of workmanship seen so far has been great be it building work, tiling, joinery or painting. Always provided a detailed timeline and schedule about the work. They even put extra hours and days for us to move back home. Everyday after work they tidy up. Even neighbours have given good feedback that they are unlike other builders who make lot of noise. Those minor things really matter when it comes to big jobs. They are fully committed to the job. I would highly recommend Vascontractors to anyone looking for big/small builds and making it a joyful experience for them.

Extensions- 21 Jan 2023
I’m a bit late adding this review but Vasile just reminded me. We are really happy with the home that Vasile built for us. It’s a Victorian terrace over 3 floors that needed a full renovation including electrical re-wiring, new plumbing etc plus a gf side and rear extension plus a loft conversion. Vasile and his team worked really hard to get us the finish we wanted. He always was on-hand to solve problems from building control to water pressure. He was always very friendly to work with and extremely respectful. We always got the impression that he wants to make his customers happy and takes pride in his work. Because of Covid and issues with materials and the labour market, our job took longer than expected but I think this was really outside of anyone’s control. We now have a really beautiful house that we love living in and it’s in no small part thanks to Vasile. I have recommended Vasile to friends already and have shown some of his potential customers round our house. They were always really impressed and inspired.

I have worked with a few builders during my time renovating properties and I can genuinely say Pat and Ed are two of the most professional, knowledgeable, hardworking and honest tradesmen I have come across. They quoted me a competitive price for my phase 1 works which included labour, all materials, skip hire, structural engineer and building control costs. I asked them to manage all aspects of the phase 1 renovation as well as organise the structural engineer and to deal with building control. The work included taking everything downstairs back to brickwork and replastering with bonding coat and multifinish plaster, replacing/replastering ceilings, building new stud walls, resizing window openings, removing parts of a chimney breast and knocking through between living room and dining room. They carried out all the work quickly and professionally and always went the extra mile to help out where they could. I was extremely happy with their work and would highly recommend them to anyone.

Kitchen Fitting- 7 Jun 2020
We liked Alex from the first meeting and the first impression was spot on. Alex did an amazing job on our kitchen, which was half initiated by another tradesman. He reviewed the work and fixed many issues, always explaining and communicating well. Our kitchen had to be adapted and had some non standard cabinets but Alex was able to do all the additional features we asked for and with a great result. He also recommended some design changes which we agreed to and love. He finished the work, reviewed everything and signed off, always with a smile which is a plus. Definitely highly recommended and we will call him again in the future for sure. Thank you Alex!

Carpentry- 2 May 2019
We initially hired Derek to build 2 shelves but ended up using him for so much more (plaster boarding, floor laying, hanging and re-sizing doors). He was quick to respond to the first ad, incredibly reasonably priced, a very friendly and helpful chap and communications were ongoing as we gave him more and more work to do. Work all completed to a high standard with Derek giving advice and guidance along the way. We will definitely be getting him back to do more in the future and I can't recommend him enough!

What to ask a Longfield extension builder before hiring?

Before hiring an extension builder in Longfield or extension building company in Longfield, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Longfield 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 Longfield 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 Longfield?

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 Longfield 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 Longfield 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.
