External mastic in Bewbush
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. We’re often asked to deal with weathered mastic that no longer stretches and joints pointed up with cement by mistake, on joints between brick and frames, render & cladding joints and façade panels.
Houses in smaller places like Bewbush can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. That is where gutter joints and wall joints tend to fail first.
There’s a 12-month guarantee on every job, large or small.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
When it isn’t the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Render that is blown, hollow or coming away
- Subsidence or other structural problems
- Cracks in the bricks or render themselves, away from the joints
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.

What affects the quote in Bewbush
Every job gets its own quote. These are the things that affect it:
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- The number and length of the joints
- Whether there’s mould to deal with
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Helping us quote
When you contact us, these details help:
- Pictures of the joints, sent by email
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.

What else we do in Bewbush
What the job involves on each surface
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Landlord and commercial work in Bewbush
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured.
What happens if it’s left?
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. Homes in smaller places like Bewbush 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.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

How it works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Parking around Bewbush is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive

Common questions in Bewbush
Is it worth replacing old sealant in an older home in Bewbush?
In most cases, yes, if it hasn’t been done for a while. Sealant is a maintenance item: how long it lasts depends on use, cleaning and exposure.
Can you help a landlord with a rental near Ifield station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly and reseal when it splits.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Where do you work from?
We work from Crawley. Our applicators cover Bewbush.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
What external mastic looks like in Bewbush
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Bewbush is part of Crawley, one of the post-war new towns. Homes here were built in phases, many of them in the post-war decades, so whole streets can have gutters, trims and wall joints reaching the end of their life together.
Schools such as The Bewbush Academy are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Ifield station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around St Alban's, an extension built onto an older house moves differently, and the joint between them takes the strain.
