Questions from Howden Hall
Is Howden Hall in your area for external mastic?
Yes, Howden Hall is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Do you work for landlords with property near Shawfair station?
Yes, landlords and agents are among the people we work for. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Do you work at height?
It depends on the building. Tell us the height, the number of joints and what’s below them, and we will confirm what access is needed.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
External mastic in Howden Hall
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. Common call-outs are for sealant that has lost its bond to the brick or render and joints with sealant missing in places, across concrete & block, copings & trims and façade panels.
On a four-storey tenement, gutter joints are a long way from the street, and a slow drip can stain and soak the stone for a long time before it’s spotted. For a building in Howden Hall, access is planned first, and shared parts may need the other owners to agree.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Why it’s worth doing now in Howden Hall
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. In a tenement flat in Howden Hall, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Check external joints each spring
- Make sure movement joints are not pointed over
- Keep high-pressure jets off the joints
- Leave the joints unpainted unless we’ve said otherwise
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges and let water in behind.
Once a joint can’t move, the wall finds another way, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to several days, depending on the building. Inside a flat in Howden Hall, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

Advice
Nearby places to Howden Hall
Also in Howden Hall
Surface by surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Howden Hall buildings and the weather
Historic houses like Melville Castle (about 2.6 miles east) are a reminder that the area around Howden Hall has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Rented homes near Shawfair station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Gracemount High School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Do you need external mastic in Howden Hall?
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
Most people get in touch after spotting something like this:
- Hard, crazed mastic that has stopped moving
- Rain getting behind render or cladding at a joint
- Weeds or debris growing in open joints
- Sealant pulling away from one side of the joint
Historic houses such as Melville Castle, about 2.6 miles east, show how far back building around Howden Hall goes.
Questions to ask before you book
- How much experience the applicator has
- How long the guarantee is
- Whether the sealant suits the joint
- How the colour is chosen
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
