Communal areas
Communal areas stay in use while we work. We work in sections so access is never blocked.
Mastic sealing in Hamister, done properly
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. Site teams most often ask us about mastic failing across several blocks on an estate and occupiers reporting cold air round windows, on balcony and threshold joints, external wall and movement joints and window and door perimeters on blocks. Searching for sealant specialists in Hamister? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
In smaller Scottish places like Hamister, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Frames on exposed elevations are where mastic typically fails first.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What sealant work can’t fix
Some faults sit outside our scope, and we say so rather than covering them up:
- Leaks from above rather than through a joint
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Leaks through the frame itself rather than the perimeter
If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think.
What we seal
- Balcony and threshold joints
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- External wall and movement joints
- Shopfronts below residential blocks
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Tell us who will meet us and how to get in at your building near Hamister. That goes into the plan alongside the quote.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.

- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Before we start on site

Cost factors for mastic joints
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- How much existing material needs removing
- The product specified
- Any access equipment needed
- The size and state of each joint
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- When you need the work done
- A wide shot and a close-up of the area
- The product your specification calls for
- The site address and postcode
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
What happens if it’s left?
Adding sealant to cyclical maintenance is an easy win. Waiting until leaks appear means working under pressure with less control over timing. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Hamister before they leak.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Looking after buildings in and around Hamister
Hamister sits close to the coast, within about 1 mile. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do; plan inspections around that. The east of Scotland, where Hamister is, gets less rain than the west. Frost and condensation on winter mornings can still delay outside mastic.
Around Hamister, a planned programme renews failed mastic across a building or estate in one go. Near Hamister, we review each elevation first so the quote covers what actually needs doing.

Common questions from Hamister clients
Do you work on the island where Hamister is?
Yes. Every Scottish council area is within our area, and that includes island locations such as Hamister. Island work is planned around ferry crossings and the weather, so photos and a full list before we travel are essential.
Does a coastal location like Hamister affect which sealant is used?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
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 external work may be moved if conditions aren’t right. Internal work is far less affected.
How many days will you need on site?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
Will residents or tenants be disturbed?
The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
