Extensions- 23 Jul 2018
Top Class Job by a Top Class Tradesman We can’t recommend Bob’s services enough! We wanted to choose a local tradesman for our brickwork on our single storey extension. We checked out this website and found his very high recommendations from previous customers. We had obtained 4 quotes prior to the job and Bob’s was not the cheapest nor the most expensive. We found his thoroughness in the quote, his vision going forward and subsequently his work ethic alongside his work colleague Gary, 2nd to none. As a team and individually Bob and Gary were punctual, polite and cheery and tidied up at the end of each day. You couldn’t ask for better from a tradesman and we want to say a huge THANKYOU to these genuinely lovely guys. We are so pleased with the quality of Bob’s work and the subsequent independent tradesmen who are completing the extension have all praised his workmanship, complimenting his work as the best they have come across. This praise speaks volumes and tells us we made a great choice. We have already asked Bob to come back later in the year to create a landscaped patio and garden area with features. This will be the perfect finish for our extension project. We are so glad to have found this quality Tradesman. Don’t hesitate to book him up! Cheers Bob! Dean & Sally

New garden fence. David Smith of Woodfield Construction Services fitted a new garden fence. They were very friendly workers who completed the work quicker than I expected with excellent results. Highly recommended. Blocked paved driveway. They were on time, very polite and presented well. They kept me informed of what they were doing and I have no hesitation in recommending them and using them again.

Extensions- 11 Feb 2022
We had to wait a few months before Rick and Lee could start, as their previous job overran. However, we're so glad we did! From start to finish they were an absolute joy to work with. Nothing was too much trouble for them and they always advised us the best way to go about things. They are a definite credit to the trade. The job is now complete and we're just waiting for the sign off from the Council. We can't recommend Skyline Southern enough. If you find Rick is booked up, that's because he's in high demand, for obvious reasons. My advice is be patient and wait, it will definitely be worth it in the end. Thank you Rick and Lee for a fantastic job!

Having just moved into a 3 bedroom house, where one of the bedrooms was far too big for my family's needs, Trevor converted the large bedroom into two smaller ones, thus creating a 4 bedroom home. Everything about the job was undertaken with great care and diligence, the workmanship was of excellent standard, everything was done within the time frame set out and all of my questions and queries were answered in full throughout. Trevor was completely professional throughout the whole process even when I changed my mind about a couple of things.

Extensions- 28 Jan 2026
Dan came round at short notice to discuss our plans for a garden room; he provided a very detailed itemised quote so we knew exactly what we would be paying for. Before committing we had multiple questions for Dan and he (very patiently!) provided clear and detailed answers. We set up a WhatsApp group with Dan and his communication with us throughout was brilliant. He kept us updated with the plan/schedule for each day, he sent us before and after pics to show progress and was always quick to respond in detail to any of our queries. We are really pleased with the finished build, it ran smoothly and it finished on time. We really appreciate Dan, Chris, Cam and Alfie's hard work and would certainly use them again for any future projects.

What to ask a Seaview extension builder before hiring?

Before hiring an extension builder in Seaview or extension building company in Seaview, 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 Seaview?

An extension builder in Seaview 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 Seaview 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 Seaview?

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 Seaview 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 Seaview 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.
