FAQs for Bilting
Do you work for landlords with property near Wye station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover smaller places like Bilting?
Yes, Bilting is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How do you reach high-level joints?
Each building is different. Send us photos and a rough idea of the height and we’ll confirm how they can be reached safely.
Can a movement joint be filled with mortar?
No. Cement or mortar cannot stretch. Where a joint has been mortared, it can often be raked out and sealed properly.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you guarantee your work?
Yes. Every job comes with our one-year guarantee.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or send us an email.
External mastic in Bilting, done properly
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render. Common call-outs are for old sealant gone brittle and cracked and rain getting behind render or cladding at a joint, on joints between brick and frames, brickwork movement joints and concrete & block.
External sealant needs dry, clean surfaces, so work around Bilting is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Keeping the joints in good condition
So the new joints stay in good condition:
- Get split or bare joints resealed while the damage is small
- Deal with leaking gutters that soak the joints below
- Leave the joints unpainted unless we have said otherwise
- Keep movement joints as flexible joints, not mortar
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick.
Why it’s worth doing now in Bilting
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. Where a wall is exposed, as many are in small places like Bilting, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

How the visit works
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work starts. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a small place like Bilting, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Mention if the joints have been sealed before

Bilting buildings and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Wye station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Wye School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Do you need external mastic in Bilting?
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
The most common problems we see are:
- Joints with sealant missing in places
- Joints pointed up with cement by mistake
- Hard, crazed mastic that has stopped moving
- Cracked joints where brick meets render or frames
If you live in an older home near Church of St Lawrence, the joints between older walls, newer extensions and the roofline need a sealant that can move.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, 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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What affects the cost of external mastic
The price is agreed before any work begins. It’s based on:
- How much old sealant there is and how hard it is to remove
- Access and height
- How many rooms, windows or areas are involved
- The size of the job
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

- Roughly how big the job is
