What affects the quote in Crosshouse
You’ll get a clear quote before we start. It takes into account:
- How many rooms, windows or areas are involved
- When we can work, for business premises

- The number and length of the joints

Asking for a quote
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that is easy
- The address or postcode of the job

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
How we handle external mastic in Crosshouse
For buildings in Crosshouse, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you are dealing with moss and dirt in joints with no sealant left and sealant pulling away from one side of the joint, we can help.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
You get a 12-month guarantee, the same in Crosshouse as everywhere else we work.

What happens if it’s left?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please send an email to info@mrmastic.co.uk.
Why Crosshouse customers choose us
- Neat joints and a tidy finish
- Arbo and Everbuild products
- White, clear, grey or coloured to suit, where the product allows
- Every job guaranteed for a year
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

What do you put in the joint?

As a guide, most jobs take anything from a few hours to several days, depending on the building. Bigger jobs take longer, and we will tell you how long to expect.

Yes. We cut out all the old sealant and clean the joint before resealing.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months.
Walls and rooflines in Crosshouse
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Schools such as Greenfaulds High School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Greenfaulds station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Tell anyone working on the walls about the movement joints
- Fix overflowing gutters above sealed joints
- Do not let climbing plants root in the sealant
- Make sure movement joints aren’t pointed over
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.

When something else is needed
In fairness, some problems need a different trade:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracking across the wall rather than at a joint
- Damp that isn’t coming from the joint
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.

What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the building. Outdoor work around Crosshouse depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises
