Tyler's Hill buildings and the weather
With historic houses such as Chenies Manor House (about 3 miles south-east) nearby, there’s older building stock in the area around Tyler's Hill as well as newer homes. 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Ley Hill School, larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Amersham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to St George's Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

About our external mastic in Tyler's Hill
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. Typical jobs include weathered mastic that no longer stretches and failed sealant between panels on a façade, across brickwork movement joints, concrete & block and façade panels.
Somewhere as small as Tyler's Hill, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
There’s a 12-month guarantee on every job, large or small.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Make sure movement joints aren’t pointed over
- Check the sealant is paintable before painting near it
- Look over the joints every year, ideally after winter
- Keep soil, plants and ivy away from the joints
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. In a small place like Tyler's Hill, 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.
- 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

Related advice
Surface by surface
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
FAQs for Tyler's Hill
Do you work for landlords with property near Amersham station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Do you cover smaller places like Tyler's Hill?
Yes. Tyler's Hill is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Rising or penetrating damp from elsewhere in the wall
- Adding movement joints to masonry that has none
- Loose or hollow render, which needs re-rendering
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.

What affects the cost of external mastic

- The type of sealant required
- Whether there’s mould to deal with
- The old material and how stubborn it is
- When we can work, for business premises
Every job is a little different, so each one gets its own quote. 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.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How we’d reach the joints
- Whether it’s a home or a business
- The rough size of the job
