About our external mastic in Tylers Green
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. Common call-outs are for cracked joints where brick meets render or frames and brick movement joints where the sealant has split, across façade panels, render & cladding joints and brickwork movement joints.
Houses in smaller places like Tylers Green can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. That’s where gutter joints and wall joints tend to fail first.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

What external mastic looks like in Tylers Green
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Hughenden Manor (about 2.4 miles west) are a reminder that the area around Tylers Green has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near High Wycombe station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. In the older streets around Church of St Margaret, an extension built onto an older house moves differently, and the joint between them takes the strain.
Tylers Green is about 2 miles north-east of High Wycombe, in Buckinghamshire.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Common problems we fix in Tylers Green
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Look out for these signs:
- Leaking joints around cladding and façade panels
- Rain getting behind render or cladding at a joint
- Sealant pulling away from one side of the joint
- Hard, crazed mastic that has stopped moving
If you look after a building such as Manor Farm Community Infant School, its movement joints, gutters and trims need looking after like any other building’s.
Before you book anyone
- Is VAT in the price?
- The length of the guarantee
- Whether they’re fully insured
- Who does the work, and how experienced they are
What happens if it’s left?
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way. Around Tylers Green, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

Tylers Green: your questions answered
Will you come out to Tylers Green?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near High Wycombe station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
What the job involves on each surface
Cladding and façade panels
If the façade has a specified sealant, that is what we use, or one the system allows. Tell us what the building has when you get in touch.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly if the joint can be cleared.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Act on the first splits you see
- Ask before painting over external sealant
- Look over the joints every year, ideally after winter
- Never let anyone fill a movement joint with mortar
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
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.

What happens on the day
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for a handful of joints, longer for a whole elevation. For a job in Tylers Green, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.

- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
