Outside joints around Peppard Hill
London and the South East are among 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 Greys Court (about 1.9 miles north-east) nearby, there’s older building stock in the area around Peppard Hill 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.
Rented homes near Henley-On-Thames station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Peppard Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Peppard Hill: your questions answered
Will you come out to Peppard Hill?
Yes. Peppard Hill is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do external mastic in Peppard Hill?
Yes, Peppard Hill is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. Colour is agreed with you before we begin, matched as closely as the range allows.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
How long does external mastic last?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Ask before painting over external sealant
- Don’t let climbing plants root in the sealant
- Check external joints each spring
- Keep movement joints as flexible joints, not mortar
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
What affects the cost of external mastic
We quote each job individually. This is what makes a difference:
- Whether the work is at height
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.
Helping us quote
When you call or email, it’s useful to know:
- Whether it has been sealed before
- The address or postcode of the job
- The type of property
- What’s wrong with the joints now
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or send us an email.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
How it works
We keep the work tidy and contained to the joints we are treating. Expect the work to take anything from a few hours to several days, depending on the building. For a village or hamlet like Peppard Hill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Mention any tricky access
- Tell us about any water getting in
- Let us know about parking restrictions

What we are called out for in Peppard Hill
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Keep an eye out for any of the following:
- Weathered mastic that no longer stretches
- Rain getting behind render or cladding at a joint
- Failed seals between different materials
- Joints with sealant missing in places
In the older streets around The Church of Christ the King, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- How hidden problems are handled
- What the cure time is
- Are they insured?
- Whether VAT is included
Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. Around Peppard Hill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
