Weatherproofing
Sealing your walls with an external masonry water repellent cream will not only prevent water penetration but it will also preserve the life of the masonry. We have used many of the products available and only use the highest quality. masonry water repellent cream is absorbed into the substrate by up to 18mm this provides far better protection and durability than any topical silicone water repellent.
Coastal Wall Ties are approved contractors of Secotherm masonry water repellent. Secotherm is a great product that can be applied to most substrates providing they have not been painted and is guaranteed for 20 years.

Secotherm keeps your walls dry and has been recognized for it’s energy saving ability, it can be painted or sprayed on to your property and will be absorbed into the substrate, leaving you with a invisible barrier. Secotherm is breathable and completely waterproof.
The benefits of weatherproofing your masonry walls are:
- It will slow down the deterioration of the masonry materials.
- It will prevent water penetration.
- It can save energy by keeping your bricks completely dry.
We often suggest this weather proofing solution as an alternative to getting cavity wall insulation installed.

EXCELLENT Based on 62 reviews Posted on Google David BennetTrustindex verifies that the original source of the review is Google. Excellent, honest diagnosis immediately without any fuss, will use this company againPosted on Google Jason BuchananTrustindex verifies that the original source of the review is Google. We had some wall ties replaced by Coastal Wall Ties and the work was excellent. The wall also needed repointing so it was a great way to combine both jobs and we are very pleased we chose CWT. Alex's advice was spot-on and the work was completed to a very high standard, and quickly. We spoke with a number of companies before going ahead with this work and are glad we chose this firm. Would highly recommend.Posted on Google Gordon RangerTrustindex verifies that the original source of the review is Google. Alex did an excellent job on our leaky lintel. When it became clear that his original proposed fix was not possible as the original lintel type is no longer made, he quickly suggested an equally effective (and cheaper!) alternative solution. Very happy to recommend him.Posted on Google Emma BernagozziTrustindex verifies that the original source of the review is Google. Alex was fantastic, the work he completed for us was excellent - replacing our wall ties, repairing a lintel and a number of cracks in the mortar. He was professional, took the time to explain the work he was doing and cleaned up thoroughly after himself every day. He offered advice, on other areas of required work, which was much appreciated and was polite and considerate. Would highly recommend him and Coastal Wall Ties.Posted on Google Raj PatelTrustindex verifies that the original source of the review is Google. Alex has done an amazing job replacing my wall ties and kitchen window lintel. He was efficient, excellent at communicating and very knowledgeable. I would highly recommend him!Posted on Google Connor MurphyTrustindex verifies that the original source of the review is Google. Damp works. Recommended. Alex is very informative, explaining the process all the way through. Made time to answer all my questions and give me that extra bit of knowledge. Nice tidy job.Posted on Google Ben GutierrezTrustindex verifies that the original source of the review is Google. Very competitive price. The bricks look nearly new and the Pointing looks superb! Work was done efficiently and to a very high standard. Would highly recommendPosted on Google Matthew PollardTrustindex verifies that the original source of the review is Google. Great company, Alex was clean and tidy worker, got the job done and all for a great price. Highly recommendable. Thanks.Posted on Google Amy SandsTrustindex verifies that the original source of the review is Google. We had used another company to remove paint from our brickwork at the front of the house and were left disappointed that a lot of stubborn paint was left behind making the front of our house look scruffy. Alex was able to remove almost all these marks and has left our brickwork looking much cleaner, thanks so much!Posted on Google Michelle DyneTrustindex verifies that the original source of the review is Google. Excellent service, very professional and went over and above to finish the job, gave me a quote which I thought was fair but when it came to do the work realised not all bricks needed work, so reduced the price, not all trades people are that honest! I would definitely use again if needed and have no hesitation in recommending Coastal Wall Ties. If you need repointing or wall ties then Coastal Wall Ties should be your first port of call.
