Boughton Corner: your questions answered
Will you come out to Boughton Corner?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Boughton Corner for external mastic?
Yes. Our work covers London and the South East, and Boughton Corner is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
What colours does the sealant come in?
The sealant colour is picked to suit the wall so the joint blends in. Exterior sealants come in a good range of colours.
How long before the joint can be used?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
Are you fully insured?
Yes, we’re fully insured for every job we do.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can landlords and businesses book you?
Yes, often. Several properties can go on one quote.
External mastic in Boughton Corner
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. Common call-outs are for movement joints filled with mortar instead of sealant and water getting into walls through failed joints, on concrete & block, joints between brick and frames and brickwork movement joints.
Outside joints can only be sealed when they’re dry, so work in Boughton Corner is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Every job is covered by our 12-month guarantee.

What external mastic looks like in Boughton Corner
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Godinton House (about 4.4 miles south-west) nearby, there’s older building stock in the area around Boughton Corner as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like Lady Joanna Thornhill Endowed Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. In the older streets around All Saints’ Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It normally takes anything from a few hours to several days, depending on the building. In a small place like Boughton Corner, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

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.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What affects the quote in Boughton Corner
You will get a clear quote before work begins. It’s based on:
- How easy the joints are to reach
- Which sealant suits the joint
- How many areas need sealing
- Mould in or behind the old joints
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Helping us quote
When you contact us, it’s useful to know:
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- A few pictures by email, if you can
To get a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
Signs you need external mastic in Boughton Corner
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Any of these means the joints need attention:
- Movement joints filled with mortar instead of sealant
- Weeds or debris growing in open joints
- Joints where the bead has come unstuck
- Gaps where render, brick and frames meet
Rented homes near Wye station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Before booking anyone
- How the colour is chosen
- Who turns up on the day
- What preparation is included
- Which sealant they’ll use, and why
What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so these are the limits:
- Render that is blown, hollow or coming away
- Cracks in the bricks or render themselves, away from the joints
- Subsidence or other structural problems
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
Joints and surfaces we work on
- Copings & trims
- Joints between brick and frames

- Façade panels
- Concrete & block
- Render & cladding joints
Why it’s worth doing now in Boughton Corner
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. Where a wall is exposed, as many are in small places like Boughton Corner, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
