External mastic for homes and businesses in Taplow
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you have plants rooting in failed movement joints and joints where the bead has come unstuck, we can put it right.
Outside joints can only be sealed when they’re dry, so work in Taplow is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Tell anyone working on the walls about the movement joints
- Keep high-pressure jets off the joints
- Check external joints each spring
- Do not let climbing plants root in the sealant
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
What happens on the day
We keep the work tidy and contained to the joints we’re treating. Expect the work to take anything from a few hours to several days, depending on the building. Somewhere as small as Taplow, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
- Mention any parking rules near the property

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Advice
Why deal with it now?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. In a small place like Taplow, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Quotes for external mastic in Taplow
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- The size of the job
- The number of rooms or windows
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

Taplow buildings and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Cliveden (about 1.8 miles north) nearby, there’s older building stock in the area around Taplow as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you live in an older home near Church of St Nicolas, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as St Nicolas' Church of England Combined School, its movement joints, gutters and trims need looking after like any other building’s.

Common problems we fix in Taplow
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Signs it’s time to call us include:
- Sealant that has lost its bond to the brick or render
- Movement joints with cracked, split or missing sealant
- Gaps where render, brick and frames meet
- Movement joints filled with mortar instead of sealant
For landlords with property near Taplow station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Different surfaces, different methods
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind.

Your questions about external mastic in Taplow
Can you do external mastic in Taplow?
Yes, Taplow is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Do you work for landlords with property near Taplow station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected.
Do you use backing rod?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
Are you fully insured?
Yes, we’re fully insured for every job we do.
How do I get a quote for external mastic in Taplow?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What’s an expansion joint in brickwork?
Most straight vertical gaps in brickwork are movement joints. It gives the wall room to move and needs a flexible seal, not mortar.
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
