Blythswood Hill External Mastic

External mastic in Blythswood Hill, done properly
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, leaving it bonded to two faces so it can move with the wall. We work on copings & trims, concrete & block and render & cladding joints, and people most often call us about rain getting behind render or cladding at a joint and weathered mastic that no longer stretches.
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 Blythswood Hill, access is planned first, and shared parts may need the other owners to agree.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep soil, plants and ivy away from the joints
- Ask before painting over external sealant
- Wash walls gently around the sealant
- Point out the joints to other trades
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
What the job involves on each surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Joints between dissimilar materials
Different materials may need different primers. We prepare both faces so the sealant bonds properly.
Landlord and commercial work in Blythswood Hill
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
If you manage several properties in or around Blythswood Hill, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
External mastic in Blythswood Hill: local notes
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. With historic houses such as Tenement House (about 0.4 miles north) nearby, there’s older building stock in the area around Blythswood Hill as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around St Columba Church of Scotland, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Charing Cross (Glasgow) station, split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Glasgow Academy? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What affects the cost of external mastic
You will get a clear quote before we start. It’s based on:

- If it’s domestic, commercial or a hotel
- The address or postcode of the job

Why it’s worth doing now in Blythswood Hill
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. Private landlords in Blythswood Hill must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
