Why act early in Stratfield Mortimer
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Around Stratfield Mortimer, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- Old sealant always removed completely
- Experience in homes, commercial sites and hotels
- A choice of colours where the product allows
- Arbo and Everbuild products

What else we do in Stratfield Mortimer
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Fix overflowing gutters above sealed joints
- Avoid pressure-washing directly into sealant joints
- Walk round the building once a year and look at the joints
- Point out the joints to other trades
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
Surface by surface
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
FAQs for Stratfield Mortimer
Is Stratfield Mortimer within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Mortimer station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How long should I leave it?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Stratfield Mortimer.
Are you ARBOMaster approved?

Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What affects the quote in Stratfield Mortimer
For a quick quote, just ask. What matters most is:
- Access and height
- How many rooms, windows or areas are involved
- The product the joint needs
- The number and length of the joints
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
What to tell us for a quote
When you call or email, these details help:
- Where the property is
- How we’d reach the joints
- A few photos by email, if you can
- Whether it’s a home or a business
Asking for a quote is easy: tell us what needs doing and where. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on the building. Somewhere as small as Stratfield Mortimer, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit

Related advice
What external mastic looks like in Stratfield Mortimer
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 Stratfield Saye House (about 2.7 miles south-east) nearby, there’s older building stock in the area around Stratfield Mortimer as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Schools such as Mortimer St Mary's C.E. Junior School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as Saint John The Evangelist, an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Mortimer station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
