Highlights

Jason did all the above works at my place, and more. I can’t recommend him highly enough. I had found quite a few issues after moving into my place a year ago, and he kindly talked through them all with me, he’s very knowledgeable and was really helpful. Jason didn’t push any work that didn’t need doing. He’s very honest, super reliable (I just left my keys out for him each day), sticks to budget, and gets the job done when he says he will. I would highly recommended him for all your building and ventilation needs. I will definitely be calling him again!

Good quality work and communications.

We employed Advance Construction to remove a dangerous chimney, rebuild our first floor front bay and do various other small building jobs. Jason clearly had experience and understanding of the issues, particularly with the bay. He provided a clear description and break down of the work to be done. The work took longer than expected due to weather, unforeseen problems encountered and changes requuired by Building Control, throughout Jason kept us informed and involved in decision making about the best way to approach the problems encountered. Communications were good throughout. The work has generally been done to a high standard and we would recommend him to others.

Great Work

I recently had Jason carry out work at my home to install a damp proof course where none previously existed, and I couldn’t be more impressed with the results. From start to finish, Jason demonstrated exceptional knowledge and truly outstanding workmanship. He arrived promptly each day and worked exactly to the agreed schedule, which gave me complete confidence in the project. His pricing was very competitive, and the quality of his work far exceeded expectations. Jason was courteous, professional, and respectful throughout, always ensuring the house was cleaned and tidied at the end of each day. What really stood out was his integrity. During the job, he identified additional work that needed doing, something that wasn’t part of the original estimate, and he completed it without charging anything extra. That level of service is rare and hugely appreciated. I can wholeheartedly recommend Jason. His reliability, expertise, and commitment to doing the job properly make him an exceptional tradesman. I would not hesitate to hire him again.

Ventilation for a slightly damp cellar

I had a cellar that was a little to damp for our liking. Jason first gave a phone consultation and suggested one approach. Unfortunately that approach didn't work due to the setup of the house so he suggested an alternate plan to install two telescopic ventilators. These were installed within a couple of weeks at a very reasonable price. He and his son are great and I would highly recommend them.

Repointing work

We needed some repointing work carried out on the NW side of the property. Excellent communication from Jason. Agreed a price and a date for the works. Arrived on time and carried out the repairs to a high standard. Very satisfied customer, would recommend and use again.

Great work at a reasonable price

Jason and team recently installed an injected damp course and repointed some brickwork at my new home. Jason was courteous, professional, and did a great job. Jason took the time to take a through set of photos and videos of his work and even added some extra touches to ensure the house was fully watertight during his visit. What stuck out to me most was his genuine care and honesty, which can be in short supply these days. I would thoroughly recommend him to anyone and look forward to benefitting from his expertise again in the future.

A definite trusted trader!

After years of fighting with damp both inside and out, I finally searched the web after having a baby to get the problem solved asap. I came across Jason and his team who responded quickly to investigate the cause and what work needed to be done, the timeframe and the cost. Everything was all clear, work was finished sooner than said and all the mess was cleaned up. Jason checked in after the works were carried out to make sure we were happy and I cannot praise the team and the work enough! Highly recommend! Extremely knowledgeable in all areas of building work! Thanks again guys.

A very smooth experience!

Jason visited in late October and undertook the damp proofing work in early December. Turned up when he said he would, was courteous and polite. Did a very professional job - explained what he was doing and why. Was neat, clean and tidy. Apologised that he couldn’t get the perfect plaster finish due to the cramped space and the presence of pipes. When I looked - he’d done a fantastic job. Highly recommend Jason and a pleasure to do business with.

Excellent work

Jason and his son carried out a variety of damp work inside and outside our house, to a very high standard and at a competitive rate. Jason made it very clear from the outset the cost of the work that needed doing and kept to that cost. Jason has completed work on our house a number of times over the past 10 years and I do not hesitate to recommend him to others. He’s very friendly, polite, punctual, works efficiently and clears up any mess. Thank you so much, Jason (and son!).

Excellent

Jason has been amazing at finding solutions for damp/condensation and leak problems. He has arranged a PIV system, repaired a flat roof and resolved dampness in a fire place hearth. He is highly recommended.

Great job!

We used Jason and team to tank two rooms in our old Victorian house, we were really struggling with damp. We have a dog that isn't great with strangers, so we actually had to vacate while the work was being done. Given that Jason and team were Which? trusted traders we felt much better about this. The communication around the work was great, we were sent lots of update photos while we were away. The 'after care' support was also incredibly helpful, as we went on to have some additional work done and Jason had no issues supporting me with any questions, ensuring nothing would impact the work he had done. I have already recommend Jason and team to other neighbors and they would be my first check point for any work that needs to be done in the future. I felt the cost of the work was very reasonable, and we were very happy with the way that the house was left!

Highly recommended for damp service

I was in desperate need of a damp survey for my buyer”s lender and found the company on the Which website. I contacted Jason and same day I managed to secure an appointment, which was within 2 days. Jason was professional and I cannot believe how honest he was, compared to other companies who were a complete rip off. I was given sound advice and Jason did the educational piece by clearly articulating issues, how it happened and suggested cost effective solutions. I wish I had found Jason before. Jason made an assessment on the internal and external parts of the house and took moisture readings. His prices are very reasonable compared to other companies I was looking at. The quote for the remediation work was also very reasonable, something I will be going for. I also received a detailed professional report within 2 days. I was so impressed l, that I have recommended the company and Jason to others

A great job on time and budget delivered with a smile

If you have any damp related issues at home you can do no better than get in touch with Advance Construction Solutions. Jason and team were very responsive and quickly identified the root cause. The solution involved injecting a new DPC into brickwork, repointing, a new sand and cement waterproof plinth and the sealing of some external brickwork. The work was undertaken on time and budget. Jason was keen to keep us informed of progress on the day and there was no way they were going to leave site without us being completely satisfied with the work undertaken first - an excellent customer service approach! This is the second time Advance Construction Solutions have undertaken work for us and I cannot recommend them highly enough.

Damp proofing and new air bricks fitted

I'm very pleased with the work that Jason did. He was very personable, gave excellent advice and did a really smart, professional job in a reasonable timescale. He went the extra mile to make sure that I was satisfied with the results and that the area was left clean and tidy. The work was completed for the amount quoted and he was also kind enough to do a couple of small related extra jobs for free - which was much appreciated. I'd be sure to contact him if I need any similar work done in future.

Excellent - would highly recommend

I can thoroughly recommend Jason, as he has recently completed a soundproofing project in my home, and has also replaced the ceiling in my shower. When I first contacted him I was impressed by his obvious knowledge of the subject, and his suggestions as to what could be done. He is happy to answer any queries, turns up when he says he is going to, and always returns your calls. He has a very pleasant, friendly personality, and instils confidence. His work is excellent and I would definitely use him in the future on any project.

Highly recommend Jason for all your building & ventilation needs!

I found Jason on this website and made contact with him after reading the reviews. He got back to me straight away, was courteous and super helpful, and came round to look at the work and give me a quote. Because he is understandably popular he couldn’t start my work for 3 months, but he gave me an exact date he could start the work and he stuck to it. He also quoted me for everything upfront, and always stuck to budget. He was very honest and told me if he didn’t think something was necessary, and also helpfully pointed out a few things I hadn’t noticed that were necessary. I left my house keys out for Jason each day (I was at work) as I knew I could trust him completely. He went above and beyond to kindly help me with a couple of extra things that popped up whilst he was at mine doing the agreed work. He knows about everything, particularly ventilation and damp. I cannot recommend him highly enough, and will be calling him again in the future for anything else I need! Top bloke, and great to chat to as well! Things he did for get included.. - resurfacing a flat roof (resin paint) - new guttering - new airbricks - installed a ventilation system - got scaffolding up and resealed a leaking chimney plus painted the side of the house with storm dry - sorted out a huge crack in my chimney breast & rendered it after too Many other jobs on my shopping list of issues too. Jason is great, drop him an email 👍

Damp Proofing Party Wall of an 1870s Cottage in Bushey

The party wall in one room suffered from rising damp to a height of around 30cms. The work carried out was an injection of waterproofing solution into the brickwork, cement rendering infused with resin and a top coat of plaster. After 5 weeks the work is showing no trace of damp penetration and has effectively cured the problem. Other work was being carried out at the time and there was a lot of building dust and dirt on the floor and other surfaces. Despite this Jason made a very creditable job in clearing up after himself. He also advised on other aspects of work being carried out by myself which I found invaluable. The work was carried out to time and budget with no onsite issues. A generous and very helpful individual whose work I would recommend.

Roofing isn't licensed, so anyone can set up - and it's a trade with more than its share of cowboys. A big re-roof must meet building regulations; CompetentRoofer (the Government-authorised NFRC scheme) registers roofers who can self-certify that, and vets and inspects them at least twice a year. Check they're on it before you hire.

Check the CompetentRoofer register
Never agree to roof work from a cold-caller at your door or an unsolicited 'we noticed your roof' note. That is the classic roofing scam.
Get a written quote that itemises access (scaffolding or a tower), the exact materials, and the workmanship guarantee, not a vague day rate.
Be wary of demands for a large cash deposit; agree staged payments against work you can actually see completed.
