1. Madden Contracts

Address: 55 – 59 Adelaide St, Belfast BT2 8FE, United Kingdom
Contact Details: +442890817200
Operating Hours: 8 AM–6 PM
Madden Contracts stood out to me for its hands-on project management. They started by giving us a single point of contact. It made it easy to keep everything on track in the timeline and to sort out hiccups immediately.
They have over 50 years of experience in the building business, especially in residential construction. I felt assured that my project was in good hands since they’ve already worked on almost everything from new builds to extensions.
The contract that I had with them was also quite flexible. I was able to make last-minute changes without everything going haywire. So if you’re the type to tweak designs a bit, it’s no big deal with them.
They gave me a detailed quote and a solid 20-year warranty. They’re even a member of the Federation of Master Builders. It’s long enough to provide me or anyone with peace of mind about the quality and durability of their work.
But I talked to some customers who had problems with meeting their timelines. They felt that they lacked regular check-ins, which could have helped catch those delays. This is one aspect that they can improve on.
Excellent workmanship
“I hired Madden Contracts last August to build a bathroom extension. Niall was our main contact and let us know what the price and schedule would be. We are delighted with our new build. The workmanship was exemplary and the guys were punctual every morning. They were a great bunch of people to get to know. Niall, Michael, Sean etc.. thanks very much.👍”

2. PK Builders

Address: Mount Eagles, Dunmurry, Belfast BT17 0WX, United Kingdom
Contact Details: +447874276722
Operating Hours: 8 AM–6 PM
PK Builders is one of my go-tos when building residential projects. I’ve tried and tested them in my home extensions, room conversions, or expanding our home. They offer free quotes and estimates so that you won’t be surprised with the bill later.
Their team has over 50 years of experience, and what’s great is that they’re all fully insured and have secured builder qualifications. It’s a great assurance that I’m working with capable professionals in the field.
They’re also CRS-qualified, which means they follow industry standards. This is crucial for me since they’ll handle what my family will live in for years. It’s important to know that they’re keeping everything up to date with construction.
They laid out everything in a written contract with breakdowns and estimates. The payment options were also helpful for someone like me who was on a budget. It’s great that they considered all of that for the project.
But I did hear some complaints about scheduling conflicts with them. They experienced delays that threw off their plans. To address this, they should implement a more solid project management system, work on realistic timelines, and give regular updates.
Excellent and attentive service
“PK Builders did a fantastic job on our kitchen extension/renovation. Kieran was very attentive to all our needs and ensured all our requirements within the brief were fully met. I’d have no hesitation in recommending PK Builders to anyone considering building or kitchen extension work.”
– Hugh Mulholland, Google Reviews
Highly efficient and professional service
“PK builders come highly recommended from me! Kieran and the team were absolutely fab! Excellent communication, workmanship and super efficient! They made some great suggestions along the way which either saved me money or gave me good ideas for all the wee details I hadn’t thought about. They really made the build as pain free as possible. The progress between the 2 pics happened in just 12 weeks and we were able to stay living there. Absolutely delighted! Thanks to all the team 👍🏼”

3. Praxis Construction N.I. Ltd

Address: 227 Woodstock Rd, Belfast BT6 8PQ, United Kingdom
Contact Details: +447835014241
Operating Hours: 9 AM–6:30 PM
Praxis Construction N.I. Ltd. has been in the building game for over 40 years. From residential renovations to commercial builds, they’ve packed all the experience to deliver quality work.
I once visited their showroom and had fun with their interactive and kid-friendly simulations. They helped me visualize my project. It’s like building your Sims house in real life.
What stood out to me, though, is their commitment to training and development. Their team trains with the top manufacturers, so I’m sure they’re always up to speed with the latest trends in the construction world.
It was also easy consulting with them. Within 48 hours, they already gave me a detailed quote and a contract that covered all the bases for all my needs. There were also no surprises down the road, so I was able to manage my budget efficiently.
That said, I’ve heard from former clients that they had communication gaps, like not being updated with construction and delays. A good way for them to tackle this is to provide a weekly progress report so clients are always in the loop on the project.
Excellent service
“While not a particularly big job Praxis Builders were quite simply outstanding! Surveyed the under bay window damp problem & brought in an excellent team of tradespeople to strip off old plaster, trace root cause of the problem & take remedial action including a new localised damp proof course. Replaced plaster & joinery over 3 separate days. Always arrived on day/time agreed & covered floor as well as cleaned up fully. I could not recommend the Company any higher. Very easy to deal with. First class job 🙂”

Professional and reliable service
“Great experience with Stephen and his team. All quotes given up front and no deviation from this, work completed in a really good time frame, great communication throughout. Trustworthy. Left our home spotless. Provided really sensible advice and multiple options for work we required allowing us to make informed decisions of what would work best for our family. Would highly recommend. Thanks again.”

4. The Method Group

Address: 5 Franklyn Park, Lurgan, Craigavon BT66 7AJ, United Kingdom
Contact Details: +447711222331
Operating Hours: 8 AM–5 PM
The Method Group is a great partner for collaborations when it comes to residential projects and even commercial builds. I’ve worked closely with them, together with their architects and designers, on a lot of projects.
What stood out for me is their commitment to sustainability. After listening to my plans and needs for the project, they crafted energy-efficient designs. It’s great to see that our house looks better and will help save energy costs over time.
They’re known for using high-quality materials and applying innovative construction techniques, which I’ve experienced firsthand. Their expertise helped us finish the project quickly.
They also handle specialized services like woodwork, building refurbishment, or even commercial fit-outs. You can use them not only for your home renovations but also for business projects.
I did hear from other clients that they faced issues with the company’s after-project response. They saw some minor defects, but these weren’t addressed promptly. It would be great if they had a team for post-completion follow-ups to prevent this.
High-quality work and reliable service
TMG recently completed a garage conversion, kitchen upgrade and bathroom construction for us. From the outset, and throughout the project, communication was excellent. Chris’s team were fantastic – there when he said they would be, first class quality of work and tidy at the end of each day. Throughout the work Chris was on site regularly and guided me through each decision that needed to be made. He found good solutions to each challenge and we are delighted with the results. Thanks again for a fabulous job!

Professional and client-focused service
“Chris was excellent right from the start of my recent renovation project. Very approachable and always listened to what I wanted and hoped for. Excellent ideas and knowledge from start to finish, nothing was too much bother and was always contactable throughout. He has a great relationship with other trades involved and took a lot of the stress out of it for me. The quality of the finish speaks for itself, I have a stunning home now thanks to him and his team’s hard work. I wouldn’t hesitate to contact the Method Group for any future work.”

5. Sloan Quality Construction

Address: Craigavon BT66, United Kingdom
Contact Details: +447510912752
Operating Hours: 8 AM–5 PM
Sloan Quality Construction is all about improving homes in Belfast and nearby areas. They caught my attention because they rarely neglect green building practices. Now, that’s a real effort to be eco-friendly.
I love that they use energy-efficient designs and materials so our home will have less environmental impact. I’ve worked with them on home remodeling and, even later, extensions. They were pros at bringing our old places back to life.
They’re also open to customization. They’ve worked closely with me and provided personalized solutions for my home restoration project.
They can also handle larger projects with their project management services if you have a bigger project. My friends tried them with their businesses and told me their building plan was executed efficiently.
Now, some clients pointed out the absence of liability insurance details from them. This can be a factor, especially when handling larger projects. So, Sloan Construction should clarify this and post more information on their website and other materials.
Meticulous and client-centered service
“We had some broken tiles in our garage and wanted to just replace what was needed without making things look mismatched and sloppy. Jim was very supportive and gave us great ideas. A very professional job! He always showed up on time very polite and with a great attitude despite the heat as it was summer and the temperatures were around 30 degrees Fahrenheit. He was very detail oriented, including ensuring the levelness of the tiles. We are very happy with the results and highly recommend Jim for any job.”
