About our external mastic in Quarley
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. If you’re dealing with weeds or debris growing in open joints and sealant that has lost its bond to the brick or render, we can put it right.
Older homes in small places like Quarley may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
Each job carries a 12-month guarantee, whatever its size.

Different surfaces, different methods
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it and keep the sealant to the right depth.
How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Quarley, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at every joint and agree a colour to suit the wall.
- 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.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
Ask for a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
Advice
Common questions in Quarley
Do you work for landlords with property near Grateley station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Is Quarley in your area for external mastic?
Yes. We work across London and the South East, and Quarley is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Is it OK to fill a movement joint with cement?
No. Cement or mortar can’t stretch. If it has already been filled, we can normally cut it out and reseal it.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Why do you put foam in the joint first?
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 bead can stretch.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Signs you need external mastic in Quarley
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Keep an eye out for any of the following:
- Gaps where render, brick and frames meet
- Brick movement joints where the sealant has split
- Old sealant gone brittle and cracked
- Water getting into walls through failed joints
If you live in an older home near Church of St Michael, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What else we do in Quarley
Leave it or put it right?
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. In a small place like Quarley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

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:
- Any mould that needs treating
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- How much there is to do
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear price before work begins.
Asking for a quote
You do not need to know the technical terms. Just tell us:
- How many joints, rooms or windows are involved
- The problem you’ve noticed
- Any previous sealing or DIY work
- Where the property is
For external mastic in Quarley, ring 0345 464 0079 or send us an email. Tell us what the problem is and where, and you will get a clear quote before we start.
What sealant work cannot fix
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Movement that is more than a sealant joint can take
- 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
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before booking.
