About our external mastic in Home Farm
On houses, flats and commercial buildings across Home Farm, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on joints between brick and frames, copings & trims and render & cladding joints, and common reasons people get in touch are damp patches traced to an open external joint and joints with sealant missing in places.
Outside joints can only be sealed when they’re dry, so work in Home Farm is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
All our work is covered by our one-year guarantee, wherever you are in Bracknell Forest.

Home Farm: your questions answered
Can you help a landlord with a rental near Bracknell station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Should the sealant in an older Home Farm home be renewed?
In most cases, yes, if it hasn’t been done for a while. Sealant is a maintenance item: how long it lasts depends on use, cleaning and exposure, and many homes in Home Farm may already be on their second or third set.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Where are you based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can you seal joints between two different materials?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides, primed where needed.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
What happens on the day
The work is kept neat and contained to the area we are working on. Expect the work to take anything from a few hours to several days, depending on the building, and we explain the cure time before we leave. In a small place like Home Farm, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Keep high-pressure jets off the joints
- Keep movement joints as flexible joints, not mortar
- Clear growth from the base of walls and joints
- Look over the joints every year, ideally after winter
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
How we quote for external mastic
Every job gets its own quote. These are the things that affect it:
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
- The number of rooms or windows
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Photos by email, if that is easy
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
For external mastic in Home Farm, phone 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and you’ll get a clear quote before any work starts.
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Leave it or put it right?
Resealing a run of joints in one go is generally better than patching one at a time. Joints of the same age tend to fail together, and access only has to be arranged once. Around Home Farm, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.
What you get with us

What we are called out for in Home Farm
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.
It’s worth asking for a quote if you see:
- Moss and dirt in joints with no sealant left
- Brick movement joints where the sealant has split
- Hard, crazed mastic that has stopped moving
- Sealant that has lost its bond to the brick or render
If you let a flat or house near Bracknell station, outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before you book
- What insurance they hold
- What preparation is included
- How the colour is chosen
- Is the old sealant removed completely?
What external mastic looks like in Home Farm
Bracknell, which Home Farm is part of, is one of England’s post-war new towns. Many homes date from the post-war decades and were built in phases, so whole streets can have gutters, trims and wall joints reaching the end of their life together. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Wooden Hill Primary and Nursery School, larger buildings have long runs of movement joint that eventually need resealing. In the older streets around St Michael and St Mary Magdalene's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
