Mastic sealing in Keills, done properly
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. We work on window and door perimeters on blocks, communal entrances and stairwells and balcony and threshold joints, and the failures we’re asked to look at most are communal area joints that look neglected and brittle perimeter mastic across a building. Searching for sealant specialists in Keills? We’ve been sealing commercial buildings since 2005.
Travel to smaller places like Keills is planned so several buildings can be done on one trip. A list of addresses and photographs lets us quote for them together.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Questions we’re asked in Keills
Can one quote cover a number of our buildings near Keills?
Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.
Is Keills off your patch?
Not at all. Keills is within our area. We cover the whole of Scotland. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we’ll price the work to it.
How long does a job like this take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
Block-wide mastic in Keills
Keills lies within about 1 mile of the sea. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do; plan inspections around that. Keills is on Scotland’s wetter western side. The weather side of a block usually needs attention first. Programmes allow for wet days.
For a building around Keills, a look at every elevation first shows which joints need renewing now and which can wait.
Keills is in Argyll and Bute. Commercial clients in Keills use us for work on mastic joints. Across Argyll and Bute, 124 places are covered, including Keills. For work in that direction, see our Glasgow page.
Anyone looking for mastic sealing in PA46 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

Quoting for work in Keills
Before we quote, we look at:
- The site’s rules and procedures
- Working within restricted access windows
- Location, for remote and island sites
- How much there is to seal
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
What we need to price the job
A few photos plus some basic facts will normally do. Please tell us:
- Any specification or named product
- Asbestos survey details if the building is older
- Access details, including height
- A wide shot and a close-up of the area
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Common problems we fix in Keills
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and splits as the building moves.
Typical triggers for a call:
- Complaints coming in block by block
- Patchy repairs in mismatched sealant
- Water getting in round frames after rain
- Mastic failing across several blocks on an estate
Owners near Keills can renew frame and external mastic block by block on one programme.
What your quote should include
- Proof of insurance
- Whether primer will be used where the manufacturer specifies it
- Is the sealant right for the movement and the substrate?
- How the existing material will be dealt with
Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a few days for most blocks, with larger programmes scheduled building by building, and we clear our waste as we work. Travel to smaller Scottish places like Keills is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Before we start on site
- Share your working hours and any access restrictions
- Tell staff and tenants when we will be in
- Confirm the product named in the specification
Request a quote
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or send details through our quote form.
Advice

Other services in Keills
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Redoing a failed joint normally costs more than getting it right at the outset, 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.
Why deal with it now?
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Renewing every failing joint on one visit is the sensible approach for a place like Keills. Send photographs and we will quote for everything together.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
