External Mastic in Ramsgate
Professional external mastic in and around Ramsgate, with old sealant always removed completely.
- Weeds or debris growing in open joints
- Sealant that has lost its bond to the brick or render
- Rigid filler in a joint that should flex
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
- Damp that is not coming from the joint
If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

External mastic in Ramsgate, done properly
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. If you have joints with sealant missing in places and failed seals between different materials, we can help.
Ramsgate mixes older houses and their gutters with newer estates of brick, render and uPVC trims. All of those joints move, so they need a flexible sealant rather than a rigid filler.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Leave it or put it right?
A failed movement joint lets water into the wall, behind render and cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Around Ramsgate, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before work begins.
Why us?
- Experience in homes, commercial sites and hotels
- Anti-fungal sanitary silicone in wet areas
- You choose the colour before work begins
- We leave the area clean and tidy
When to call us in Ramsgate
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint can’t move, so the wall cracks somewhere else instead.
Look out for any of the following:
- Cracked joints where brick meets render or frames
- Failed sealant between panels on a façade
- Joints pointed up with cement by mistake
- Damp patches traced to an open external joint
If you live in an older home near St. Luke's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What your quote should include
- What guarantee comes with the work
- How the joint is cleaned and prepared
- Which sealant they’ll use, and why
- Whether you can choose the colour

What else we do in Ramsgate
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. A visit in Ramsgate needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed

Advice
Questions from Ramsgate
Can you do external mastic in Ramsgate?
Yes. Our work covers London and the South East, and Ramsgate is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Is external mastic in a coastal place like Ramsgate any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Where is Mr Mastic based?
We work from Crawley. We cover Ramsgate and the rest of Kent.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
What does external mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or drop us an email with a short description of the job.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Ramsgate buildings and the weather
Ramsgate is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Quex Park (about 4.4 miles north-west) are a reminder that the area around Ramsgate has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For landlords with property near Ramsgate station, split movement joints are easy to miss on a rental until damp shows inside. Schools such as Priory Infant School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
