What affects the cost of external mastic

- Mould in or behind the old joints
- Working hours on commercial sites
- The old material and how stubborn it is
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.

External mastic for homes and businesses in Benderloch
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it. We work on joints between brick and frames, render & cladding joints and concrete & block, and the jobs we see most are cracked joints where brick meets render or frames and joints with sealant missing in places.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering.
All of our work is guaranteed for twelve months, in Benderloch and everywhere else we cover.

Different surfaces, different methods
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.

External mastic in Benderloch: local notes
Benderloch is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
In and around Benderloch, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

What we do, step by step
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. The work generally takes anything from a few hours to several days, depending on the building. Outside jobs in Benderloch need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we’re working on

Advice
Questions from Benderloch
I let a flat near Connel Ferry station. Can you help?
Yes, landlords and agents are among the people we work for. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Is Benderloch within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours to a few days, depending on the length of joint and the access. We will tell you when we quote.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Are you insured?
Yes. We are fully insured for every job we do.
When to call us in Benderloch
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 are:
- Leaking joints around cladding and façade panels
- Rigid filler in a joint that should flex
- Water getting into walls through failed joints
- Brick movement joints where the sealant has split
For landlords with property near Connel Ferry station, split movement joints are easy to miss on a rental until damp shows inside.
What to look for in a quote
- How hidden problems are handled
- Whether the sealant suits the joint
- Whether they’re fully insured
- What the quote includes, VAT included or not
Why act early in Benderloch
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
