About our external mastic in Temple
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. We work on concrete & block, brickwork movement joints and joints between brick and frames, and the jobs we see most are movement joints filled with mortar instead of sealant and sealant pulling away from one side of the joint.
External sealant needs dry, clean surfaces, so work around Temple is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

How it works
At the end, we look at the finished work together. The visit itself normally takes anything from a few hours to several days, depending on the building, depending on the amount of work. Somewhere like Temple needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on

Different surfaces, different methods
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Temple buildings and the weather
Historic houses like Harleyford Manor (about 0.9 miles west) are a reminder that the area around Temple has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
If you live in an older home near Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Marlow station, split movement joints are easy to miss on a rental until damp shows inside.
Temple is about 2 miles south of Marlow, in Buckinghamshire. Across the SL7 area, we cover external mastic for homes and businesses. Temple is one of 263 places in Buckinghamshire where we work. You can also see our page for Reading, about 11 miles away.

What affects the quote in Temple
The quote reflects the job in front of us. We take into account:
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- Access and height
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 make a difference, and we’ll explain the quote if you ask.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- A few pictures by email, if you can
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
We quote each job on its own. Just phone 0345 464 0079 or send us an email with the details and send photos if you have them.
Questions from Temple
Can you do external mastic in Temple?
Yes, Temple is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
I let a flat near Marlow station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Will the new joint stand out?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
Is there a guarantee?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Honest limits
We will not take on work that will not last, so these are the limits:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracks in the bricks or render themselves, away from the joints
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before you book.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep soil, plants and ivy away from the joints
- Keep water from gutters off the wall
- Keep movement joints as flexible joints, not mortar
- Leave the joints unpainted unless we’ve said otherwise
Keep pressure washers away from the sealant. High-pressure water can lift the edges and let water in behind.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
Why it’s worth doing now in Temple
Sealing over the top of old mastic does not hold for long. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. Older cottages and farmhouses around Temple can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.

When to call us in Temple
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
Any of these means the joints need attention:
- Damp patches traced to an open external joint
- Weathered mastic that no longer stretches
- Movement joints with cracked, split or missing sealant
- Weeds or debris growing in open joints
If you look after a building such as Bisham Church of England Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What to look for in a quote
- When the joint can take water or movement
- Which colour the sealant will be
- Whether the sealant suits the joint
- Are they insured?
