External mastic in Palm Bay: local notes
Palm Bay is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Quex Park (about 4.3 miles south-west) nearby, there’s older building stock in the area around Palm Bay as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like Palm Bay Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. In the older streets around St Philip, an extension built onto an older house moves differently, and the joint between them takes the strain.
Palm Bay is about 1 mile north-east of Margate, in Kent. Homes, rented property, offices and hotels in Palm Bay is covered for external mastic. Every job comes with our one-year guarantee.

About our external mastic in Palm Bay
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. If you have rain getting behind render or cladding at a joint and rigid filler in a joint that should flex, we can help, on brickwork movement joints, copings & trims and render & cladding joints alike.
Older homes in small places like Palm Bay may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

For landlords and businesses
If you manage several properties in or around Palm Bay, several properties can go on one quote. Send us the addresses and the work at each.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Adding movement joints to masonry that has none
- Damp that isn’t coming from the joint
- Cracking across the wall rather than at a joint
If in doubt, phone 0345 464 0079 or email us and we will say what we think before you book.
Surfaces we seal
- Concrete & block
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
- Brickwork movement joints
- Façade panels
What the job involves on each surface
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
Your questions about external mastic in Palm Bay
I let a flat near Margate station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Will you come out to Palm Bay?
Yes. Palm Bay is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.
Can a movement joint be filled with mortar?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What happens on the day
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. The job normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Palm Bay, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
