How we handle mastic sealing in Knightswood
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. If you’re dealing with water getting in round frames after rain and occupiers reporting cold air round windows, we can help. Looking for mastic applicators who cover Knightswood? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
In Scotland’s cities, housing associations look after blocks and estates of every age. A planned programme deals with failed mastic across an estate, block by block, with residents given notice through the landlord.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to bring in a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
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.
FAQs: Knightswood
Do you cover business parks and estates near Knightswood, such as Anniesland Industrial Estate?
Yes, sites like Anniesland Industrial Estate are within our area, along with the rest of Knightswood. Photos and a short description are enough for a first look.
We manage a building near Westerton station. Can you help?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
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.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you supply RAMS and insurance details?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Do you need mastic sealing in Knightswood?
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone and the repair soon fails.
Things that typically lead to an enquiry:
- Old repairs sealed over failed mastic
- Occupiers reporting cold air round windows
- Damaged joints in communal entrances and corridors
- Damp patches beside frames
Student blocks close to universities like University of Glasgow Garscube Campus, 1.2 miles to the north-east of Knightswood, are easiest to work on between tenancies.

Looking after the joints
Regular inspection catches problems early. Specifically:
- Keep bins and bikes away from communal door frames
- Prioritise elevations facing the weather
- Mention RAMS, insurance or CSCS requirements up front
- Make it easy for occupiers to report draughts
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
Work for main contractors and building owners
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
