External mastic for homes and businesses in Elvetham Heath
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where mortar or filler would crack. We work on render & cladding joints, copings & trims and brickwork movement joints, and people most often call us about cracked joints where brick meets render or frames and failed sealant between panels on a façade.
Around Elvetham Heath, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.
Every job comes with a one-year guarantee.

What we are called out for in Elvetham Heath
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and tears as soon as the joint widens.
The problems people usually mention when they call include:
- Sealant pulling away from one side of the joint
- Weathered mastic that no longer stretches
- Plants rooting in failed movement joints
- Brick movement joints where the sealant has split
Managing a site like Elvetham Heath Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Look over the joints every year, ideally after winter
- Fix overflowing gutters above sealed joints
- Keep high-pressure jets off the joints
- Have failed joints looked at early
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
What affects the cost of external mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- How much there is to do
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- Whether there’s mould to deal with
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.
What to tell us for a quote
To make quoting easier, please include:
- If someone has resealed it before
- Where the job is, and your postcode
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work before giving you a price.
Common questions in Elvetham Heath
Can you help a landlord with a rental near Fleet 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 quote.
Do you cover smaller places like Elvetham Heath?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back, so the joint can move.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin from the range available.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, large or small.
What external mastic looks like in Elvetham Heath
The South East is one of 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 landlords with property near Fleet station, split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near Church on the Heath, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In a smaller place like Elvetham Heath, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.

- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
