About our mastic sealing in Whithorn
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. We work on window and door perimeters on blocks, communal entrances and stairwells and communal kitchens and washrooms, and the failures we’re asked to look at most are worn sealant at communal door frames and water getting in round frames after rain. Looking for mastic applicators who cover Whithorn? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Around Whithorn, outside mastic waits for dry weather and the right temperature. We agree a window with some flexibility.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

What else we do in Whithorn
How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes one or more days per building, depending on the joint lengths and the access, and we clear our waste as we work. For work around Whithorn, we aim for one trip, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.

Why deal with it now?
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Around smaller places like Whithorn, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Whithorn: questions and answers
Do you take on block-wide or estate-wide mastic work in Whithorn?
Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.
Is Whithorn too far out for you?
No. Small places get the same service as large ones. Every Scottish council area is within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you send RAMS and CSCS details before starting?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Do you work with property factors and landlords?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
What sets the cost
Your fixed quote is built from the real scope. It allows for:
- Quantities, in metres or numbers
- Location, for remote and island sites
- Phasing around occupants
- Whether old sealant has to be cut out first
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.
What we need to price the job
The more we know, the firmer the quote. When you get in touch, include:
- Approximate linear metres or a joint schedule
- Photos of the joints, close up and from further back
- The type of building and who uses it
- How the joints are reached, and at what height
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to phone 01277 525 020 or send photos by email with what you know.
When something else is needed
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Broken glass or failed sealed units
- Substrate edges that need repairing first
- Water coming in from the roof or rainwater goods
If you are not sure, just give us a call on 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Block-wide mastic in Whithorn
The sea is no more than about 3 miles from Whithorn. On buildings near the shore, the side facing the weather normally needs its mastic renewed first, and they deserve more regular inspection. Being in the west of Scotland, Whithorn gets more rain than eastern areas. Exposed elevations on blocks take a soaking and their mastic shows it. We plan block programmes with the forecast in mind.
Owners near Whithorn can renew frame and external mastic block by block on one programme. If you’re responsible for a building such as St Martin and St Ninian Catholic Church, frame and door mastic needs the same attention as any other property.
