- Plants rooting in failed movement joints
- Water getting into walls through failed joints
- Panel joints letting water in
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
External mastic for homes and businesses in Weybridge
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. Typical jobs include movement joints filled with mortar instead of sealant and plants rooting in failed movement joints, across copings & trims, joints between brick and frames and render & cladding joints.
Weybridge mixes older houses and their gutters with newer estates of brick, render and uPVC trims. Gutter joints, fascia trims and the movement joints in newer brickwork all need sealant that can flex.
Every job comes with a one-year guarantee, wherever you are in Surrey.

Weybridge questions
I let a flat near Weybridge station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is external mastic in Weybridge guaranteed?
All our work, in Weybridge and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Pointing it stops it working. A flexible sealant is the right fill.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
How do I get a quote for external mastic in Weybridge?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
How the job changes by surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. We prime where the sealant needs it before sealing.
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. We reseal them with a sealant suited to the panel material.
The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. For a job in Weybridge, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- Move anything stored near the joints
Ask for a quote
Asking for a quote is easy: tell us what needs doing and where and its rough size. A few photos by email make the job easier to understand, and we will come back to you with a quote.

Walls and rooflines in Weybridge
Historic houses like Byfleet Manor (about 2.9 miles south) are a reminder that the area around Weybridge has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as St James CofE Primary School, its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Weybridge station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. In the older streets around United Reform Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Weybridge is about 7 miles north-east of Woking, in Surrey. Wherever you are in the KT13 postcode area, we cover external mastic for homes and businesses. Our Surrey coverage runs to 395 places, and Weybridge is one of them. Our London page covers work nearby.
Work in KT13 and KT12 works the same way as everywhere else we cover. Whether your property is on High Street, Stafford Square and Park Lawn Road or a nearby road, we can help.

Local landmarks in Weybridge
Locally, jobs take us to homes and businesses close to The Grotto pub, Heathside School and Woburn Park and the streets around them. For rail, the closest station is Weybridge station, about 0.9 miles south-west of the centre.

Why deal with it now?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the damage spreads beyond the joint. In a family home in Weybridge, a failed seal around a bath or a frame lets water into places you can’t see, like the floor under a bath, the back of a panel or the inside of a wall. Left alone, that means rot, damp and a bigger repair.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

What affects the quote in Weybridge
The quote reflects the job in front of us. We take into account:
- How easy the joints are to reach
- The type of sealant required
- How many areas need sealing
- Working hours on commercial sites
Doing several joints on one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- The rough size of the job
- Photos by email, if that is easy
To get a quote, ring 0345 464 0079 or drop us an email with the location and a short description of the problem. You’ll have a clear quote before work begins.
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Keep high-pressure jets off the joints
- Fix overflowing gutters above sealed joints
- Look over the joints every year, ideally after winter
- Ask before painting over external sealant
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
