Reaching out to Polbuilt for insights on basement renovation turned out to be more informative than expected. From the first exchange, the communication was steady and straightforward.

Their team handled my inquiry personally and laid out what you could expect from their process—from structural assessments down to finishing touches like flooring and lighting. It’s clear they don’t treat basements as just extra space.

They shared examples of past work, including basement conversions turned into storage rooms, laundry areas, and even integrated utility spaces.

According to their previous clients, their team doesn’t just show up to the job—they genuinely understand how to make underused spaces more functional and solid in structure.

The only thing that didn’t quite meet expectations was their website. It works, but the layout and design are outdated. For a company delivering this level of craftsmanship, a more polished and informative online presence would help new customers see what they’re capable of upfront.

Still, Polbuilt’s experience and precision are worth noting. They’re a practical choice if you’re aiming for a well-built basement with honest communication throughout the project.

Great communication as well as craftsmanship

“Dominik and his team installed a downstairs shower room for me. This included blocking up a door, installing new windows and building a wall.  Dominik’s communication was great, giving me regular updates of where the work was at and what the next steps would be, completing the work on time and on budget. The team were great,  they worked very quietly, tidily and cleaned up very respectfully at the end of each day. They arrived dead on time every single day and were very helpful and friendly. The finished shower room is lovely. I would recommend PolBuilt.”

Provides quality, value, professionalism, and good humour

“We have used Polbuilt for a number of renovation and building projects around our house over the last 14 years. Most recently for a full loft conversion including an additional bathroom. We have always found them to be a great combination of quality, value, professionalism and good humour (which is very important when you share your house with them for 3 months)! I would strongly recommend Polbuilt to anyone looking at undertaking a building or renovation project.”

When I got in touch with Marc Allan Builders to ask about basement renovation services, the initial call was handled with professionalism and clarity. They walked me through their full-service approach—from structural assessments and insulation to flooring, electrical work and finishing.

You get the sense that their process is both structured and flexible, and that they’ve handled various home upgrades with care. Their in-house quantity surveyors and operations managers also add a layer of accountability and make corrections on their pricing.

The team didn’t oversell anything. Instead, they gave realistic timeframes, explained how additional costs are communicated, and emphasised their commitment to staying on budget.

Their past projects—especially lofts and extensions—reflect the quality and scale you’d expect from a crew with this kind of experience. Communication appears to be one of their strengths, and based on how quickly they responded to our queries, that holds up.

If there’s one downside, it’s that they don’t operate on weekends. This could be limiting if your schedule only allows for weekend site visits or coordination, so plan accordingly.

Brilliant work done to our space

“We had our loft converted by Marc and his team they done an absolutely fantastic job and having the extra space now has made a massive difference to our life as our 2 boys no longer have to share a room and they have their own space. Marc was very helpful and friendly right from the beginning and during the work been carried out the guys where all very pleasant and brilliant at their jobs nothing was every a hassle there was very minium mess and was a job very well done I was surprised how quickly from start to finished it was complete in 2 weeks I would certainly recommend Marc Allan builders to anyone looking to have any home improvements nearly 2 years on My loft which is now a bedroom still looks fantastic thanks again to everyone involved in giving us the extra living space 😀”

I reached out to Impact Glasgow to ask about basement renovation services, and the response was efficient and helpful right from the start. The staff handled my questions with clarity—breaking down costs, expected timelines, and how the process works when tackling a basement conversion.

The team didn’t overpromise anything but gave a realistic picture of what to expect in terms of permits, materials, and structural considerations. With their strong portfolio in tenement and flat renovations, it was clear they’re used to working with older properties and handling tricky layouts.

They’ve also been recognised multiple times as Building Contractor of the Year by the Scotland Prestige Awards, winning in 2021, 2023, 2024, and 2025. That gave me confidence in their track record.

Every testimonial I looked into praised their professionalism, adaptability, and workmanship. From what I gathered, the team is hands-on and stays involved throughout the entire project.

The only drawback we noted was pricing. It’s on the higher end compared to others we spoke with, so if budget is a major concern, this may impact your decision.

Impressive outcome

“Impact recently completed a total kitchen refurbishment for us. The job took several weeks and throughout we were impressed with Jason and the team who worked hard to make sure the resulting kitchen was what we wanted. Impact are not the cheapest, but they are skilful, reliable and do an excellent job – with extra touches such as progress reports. We would certainly recommend this company.”

Admirable workmanship and professionalism

“I had the chance to admire Impact’s handiwork recently at a friend’s house. He’s had his kitchen done by Impact and says he’s as pleased with the end result as he was with the entire process. Good communication thru’out, the whole team were professional and friendly and always left the place secure and tidy at the end of each day, and you can see from the pix that the standard of their work is really high.”

We visited Glasgow Joinery Services to learn more about their basement renovation work, and the first thing I noted was their weak online presence. There’s no website to review their portfolio, and their social media activity is minimal.

This makes it harder to browse previous projects or get a feel for their design approach without speaking to them directly.

That said, the visit helped fill in some of those gaps. Once I was in their office, the team was welcoming and clearly knew their craft.

They shared various joinery services they offer—from structural alterations like staircases to creating functional rooms within awkward spaces. Their experience with turning underutilised basement space into liveable rooms, including box rooms and shower rooms, felt relevant to what most homeowners in Glasgow are likely to need.

Their pricing was upfront and seemed fair for the level of workmanship and expertise.

If you’re the type who prefers a more personal consultation over clicking through project galleries, this team may suit you well.

Reliable team of experts

“John and his team are the best! They’ve done three different jobs for us now, all with distinct challenges, and they’ve all been completed to the highest standard. Besides all which, the team are very good natured, helpful and professional. Can highly recommend.”

Thomas Craig, Google Review

Pleased with regular updates

“John and his team’s quality of work was amazing. They kept me up to date with progress regularly and made sure I was happy with all the work before signing off. I can’t recommend them more highly after seeing the work they did in my flat.”

When I dropped by FIX to discuss basement renovation options, the first thing I noticed was that they’re closed on weekends. It’s not a dealbreaker, but if you need weekend consultations or site visits, it’s something to keep in mind.

Weekday availability is business as usual, and they’re easy to reach by phone during business hours. Once inside their headquarters, I met with a member who gave me a solid breakdown of what they offer—from damp-proofing and structural adjustments to plumbing, electrics, and full internal fit-outs.

What stood out was their extensive experience across a wide range of property types, including old Victorian homes. Their team handles everything in-house, which keeps the communication clear and timelines consistent.

They also explained their process for working within tight deadlines—something echoed in the feedback I’d heard during my visit.

Super satisfying services

“Many thanks to the head of the Company and his team!  They worked conscientiously, with dignity, all the stages were implemented professionally, on time, reporting and payment are phased, for which I would like to praise separately.  We were very pleased with our cooperation, we will continue to use the services of this Company”
