How much does repointing cost
The cost of repointing depends on the type of masonry being pointed: sandstone or brick, for example and the style it’s finished in: flush, bucket handle, recessed, weather struck, birds beak or tuck pointing. A further consideration is the type of repointing required: standard mortar, lime pointing mortar and coloured mortar are just some of the choices we offer. The price is usually calculated per square metre and ranges from £18-£45.
Do you use a mortar gun
No. We only use traditional methods so that we can ensure the joints are completely filled. We have many years’ experience of working in this way and achieve excellent results.
How long does pointing last
It’s difficult to assess exactly how long pointing will last as it depends on many variable factors including the type of building, its position and exposure to wind and rain, as well as the type of pointing. We can assure our customers that we are renowned repointing specialists with high standards of work backed by industry accreditations.
Cavity wall insulation removal
We issue a certificate of completion for the removal of cavity wall insulation and are happy for our customers to see the removal results for themselves, before the making good stage of the process begins.
Is it a messy job
Unfortunately some mess is inevitable, but we take every care to minimise it. Our dust extraction hoovers are a big help and we undertake a comprehensive clean-up service at the end of each day’s work.
Why do we have cavity walls
Cavity walls have been with us for quite some time. They were introduced in the 19th century and became more widely used in the 1920s. Their main purpose is to stop rain water penetrating through the walls onto the internal wall. Creating a gap between the walls allows any external rain water that soaks into the bricks to run down the back of the bricks and into the ground. Cavity wall ties are used to hold these two walls together, preventing them from moving away from each other.
Why is cavity wall insulation a problem
Cavity wall insulation is rapidly becoming a huge problem because the material used cannot withstand long periods of heavy rain penetrating the brickwork on exposed walls. Another reason is because the material was incorrectly installed under high pressure, causing the insulating material to be extremely dense. This creates a solid area which water can pass through. The insulation companies claim that the materials used are water resistant, however we know from removing the cavity wall insulation from many properties across the south coast that unfortunately cavity wall insulation is not water resistant.
How much does cavity wall tie replacement cost
Cavity wall tie replacement is relatively cheap, depending on the size of your property. In some cases, not all elevations will need work carried out. Contact us for a free inspection and quotation; we are cavity wall tie specialists.
What remedial wall ties do you use
We can install any remedial wall tie that is on the market today. It’s crucial to identify the correct wall tie for the property’s masonry material. All our remedial wall ties are made from marine grade stainless steel.
Do you have public liability insurance
Yes, we are insured to £5,000,000.
Is your work guaranteed
Our wall tie replacement comes with a 25-year transferable company guarantee; every customer also has an option of purchasing an insurance backed guarantee.

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.
