DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
How we handle external mastic in Great Wigborough
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. If you’re dealing with movement joints filled with mortar instead of sealant and brick movement joints where the sealant has split, we can put it right, on render & cladding joints, copings & trims and façade panels alike.
External sealant needs dry, clean surfaces, so work around Great Wigborough is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Check external joints each spring
- Clear growth from the base of walls and joints
- Fix overflowing gutters above sealed joints
- Show decorators and builders where the movement joints are
Do not paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
How the job changes by surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best in all weathers.
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
What we’re called out for in Great Wigborough
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
Most people get in touch after spotting something like this:
- Damp patches traced to an open external joint
- Old sealant gone brittle and cracked
- Plants rooting in failed movement joints
- Movement joints filled with mortar instead of sealant
Homes close to Church of St Stephen include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around Great Wigborough can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

Common questions in Great Wigborough
Does living near the coast affect external mastic in Great Wigborough?
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.
Will you come out to Great Wigborough?
Yes, Great Wigborough is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
What external mastic looks like in Great Wigborough
Great Wigborough is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Layer Marney Tower (about 2.8 miles north-west) nearby, there’s older building stock in the area around Great Wigborough as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
In and around Great Wigborough, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
