What external mastic looks like in Wainscott
Wainscott is within about 2 miles of 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 Restoration House (about 1.7 miles south) nearby, there’s older building stock in the area around Wainscott as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Schools such as Wainscott Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as St Philip & St James, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

About our external mastic in Wainscott
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. If you are dealing with movement joints with cracked, split or missing sealant and rain getting behind render or cladding at a joint, we can help, on façade panels, copings & trims and brickwork movement joints alike.
In a smaller place like Wainscott, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are generally the first to go.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Why act early in Wainscott
Water gets in through a failed movement joint. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Homes in smaller places like Wainscott can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Point out the joints to other trades
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
- Walk round the building once a year and look at the joints
Don’t paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants are not designed to be painted, and paint can crack as the joint moves.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
FAQs for Wainscott
Can you help a landlord with a rental near Strood station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Does the coastal weather in Wainscott affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
How often do external joints need resealing?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
What does external mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Signs you need external mastic in Wainscott
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
Look out for these signs:
- Gaps where render, brick and frames meet
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
- Rain getting behind render or cladding at a joint
Rented homes near Strood station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

How it works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. A visit to Wainscott is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
Surface by surface
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible in all weathers.
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
