Say Goodbye to Damp: Expert Solutions for Condensation, Penetrating & Rising Damp
Rising Damp
Rising damp is caused by moisture from the ground moving up through your walls, often leading to tide marks, damaged plaster, and structural problems if left untreated.
Penetrating Damp
Penetrating damp happens when water enters through external issues like cracked render or leaking gutters, resulting in damp patches and mould indoors.
Condensation
Condensation forms in areas with poor ventilation, leading to black mould, musty smells, and damp surfaces — especially during colder months in Portsmouth homes.

Lee & Mason did the work on our property and we found them to be very polite, professional and clean ..wouldn’t hesitate to recommend
“Thanks to Franky, Daniel & Sonny for all their hard work. They have worked beyond expectation”
Really found the team to be honest, upfront and very well trained in how to work in peoples homes. Great work. Regards J.
I was very please with the work the company has done. I had damp throughout the house so had damp-proofing including an injection of damp course. Given the extent of the job they completed the work efficiently and with minimum disruption. The workmen were always polite and very helpful. The finished work was excellent. Only time will tell if the damp problem has been sorted but the company made it they would come back to fix any issues. I have no doubt they are true to their word and would recommend them to anyone.
Excellent customer service! James did a very thorough survey and identified a small breach in the tanking in the basement (not fitted by them) He was very knowledgeable and did his very best to find an ‘economical’ solution. He was very honest and I was able to conclude that at this point the cost of repair far outweighed the benefits gained. Should the situation change I would definitely use them.
“The overall improvement is brilliant and the installation team were first class!”
I spoke to Jack on the phone, who was very friendly and professional. Then James performed our survey. I found James and the experience with the Home Building & Surveying Company very refreshing, compared to others I have used in the past. They were very honest in their assessment and responses, with no hidden extras, providing very valuable advice. I am, and will in the future recommend them to anyone with damp challenges.
Good lads, grafted hard and done a good job.
Great work on a damp proof course and other bits and pieces. Arrived on time and knew exactly what to do. Leagues above the other quotes. Hope I don’t need you again but would be happy to recommend.
Nathan and Kris were on time, professional and got the job done as quick as possible without missing a spot. Would highly recommend.
Really impressed with the guys and all their effort, the building looks like new and the guttering finishes it off nicely. cheers
Very happy with the work Home Building carried out at my property, very knowledge, competitive and friendly. Thanks for the hard work of your installers too they did a great job! Thanks again
Immaculate, efficient service, it wasn’t a big deal for Luke and his team. Keep up the Good work. Highly recommended.
The Home Building & Surveying Company were excellent in all departments – professional, reliable, well-informed. They resolved multiple residential issues with minimal fuss and would definitely use them again, though fingers crossed I shouldn’t need to!
Had a meeting with their surveyor Andrew yesterday 15/02/2022. I have to say he was very professional. Very happy with the quote we have been given and hoping to go ahead with the work early summer. I can’t wait to see the finished product!
Job well done, new damp course and replastering completed. Paul and Dean were excellent, tidy and kept me updated throughout.
Great company from initial call to completion. Gave quote with no hidden extras, started and finished on time – the finished product looks great. Kris & Nathan were stars of the show, arrived on time, worked hard all day, polite and personable, cleaned up when finished, a credit to the company.
Spoke to a very polite and friendly chap called Jack on the phone who explained all about the exterior painting they do, and I decided to have a survey. The surveyor Stuart was very knowledgeable, and I’ve decided to go ahead with them. There’s too many cowboys out there, so it’s nice to see such professionalism from a company for once.
“I am very pleased with the work done from the initial survey to completion of the damp treatment. I would like to particularly commend Josh & Joe as a team they were courteous, efficient & professional in their workmanship”
Booked in quickly and survey was much more in depth then expected. Felt very comfortable in our decision and was a notch above the rest.
“First class job done by two great tradesmen!”
Excellent work, professional team, left clean and tidy. Very impressed with the work.
How to Spot Damp Problems in Your Home
Damp problems won’t go away on their own — and the longer they’re left, the more damage (and cost) they can cause. If you’ve noticed any of the following warning signs, it’s time to call in the experts:
- Dark stains, flaky paint, or bubbling on walls and ceilings
- A damp, musty odour or signs of black mould near windows or in corners
- Peeling wallpaper or cracked, crumbling plaster
- Persistent condensation on windows, walls, or ceilings
- Increased allergy symptoms, asthma flare-ups, or breathing issues indoors
Act early to avoid major repairs — our Portsmouth damp surveyors can diagnose the issue, trace it to the source, and recommend a reliable, cost-effective fix.
