Mastic sealing in Perth: the local picture
The 2 miles around Perth include 13 care or nursing homes. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents. Being in the east of Scotland, Perth gets less rain than the west coast. Frost and condensation on winter mornings can still delay outside mastic. We plan block programmes with some give for it
Landlords with units on estates such as St Catherine's Retail Park, under half a mile east of Perth, can bring frame, door and external mastic across several units into one programme. Site managers at schools like Perth High School can fit frame mastic into the summer works. If you look after a block within reach of Perth station, which lies south-east of Perth, frame and balcony mastic can be renewed on one programme.

Inspect, seal, sign off: every visit follows that pattern.

- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.

Related advice
Leave it or put it right?
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go, under a single quote and a single programme. Water through a failed joint in a building in Perth can spoil ceilings, floors and stock. Early action limits what needs repairing.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Different surfaces, different methods
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
External movement joints
Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.

Questions about Perth
Will you take on a block within reach of Perth station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Does your area include sites such as St Catherine's Retail Park, near Perth?
Yes. Estates, retail parks and business parks around Perth, St Catherine's Retail Park among them, are all within reach. Photos and a short description are enough for a first look.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
