Hogganfield External Mastic
External mastic for Hogganfield and the surrounding area: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Brick movement joints where the sealant has split
- Sealant that has lost its bond to the brick or render
- Joints pointed up with cement by mistake
What happens if it’s left?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

About our external mastic in Hogganfield
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We are often asked to deal with failed sealant between panels on a façade and rain getting behind render or cladding at a joint, on render & cladding joints, brickwork movement joints and façade panels.
External sealant needs dry surfaces, so outdoor work around Hogganfield is planned around the weather. Let us know about access to every wall and roofline.
Each job carries a 12-month guarantee, whatever its size.

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Get split or bare joints resealed while the damage is small
- Look over the joints every year, ideally after winter
- Ask before painting over external sealant
- Do not let climbing plants root in the sealant
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.

How long before the joint can be used?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. We will reseal it with a flexible sealant.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the building and we leave things clean and tidy. Outdoor work around Hogganfield depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- 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.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention any tricky access
- Mention any leaks or damp you’ve noticed

Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. The sealant is chosen with that in mind.
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.
