Why it’s worth doing now in Plasterfield
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Plasterfield before they leak.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
Why appoint us
- Specification-led, product-correct work
- Fixed quotes based on photographs, drawings or a visit
- One number for every site we cover
- Old sealant cut out, never sealed over

Building owners, agents and FMs in Plasterfield
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.
Surface by surface
Window and door perimeters on blocks
We typically work through a block’s windows in a planned order. How each joint is reached is agreed at quote stage.
External movement joints
External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Glazing that needs replacing
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Frames that are rotten, warped or broken
If you are not sure, just call the office on 01277 525 020 or send photos by email and we will give you a straight answer.
Joints and surfaces we work on
- Shopfronts below residential blocks

Plasterfield: questions and answers
Can you work at a site such as Parkend Industrial Estate, by Plasterfield?
Yes, sites like Parkend Industrial Estate are within our area, along with the rest of Plasterfield. Photos and a short description are enough for a first look.
Will you travel to Plasterfield on the island?
Yes. Islands are part of our area, Plasterfield included. Ferry times and the weather set the plan, so we ask for photographs and a full list first.
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the building height and any access already in place and we will confirm the approach in the quote.
Quoting for work in Plasterfield
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Site requirements such as inductions and permits
- The total length or number of joints
- Removal of failed or old sealant
- Travel to remote or island sites
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- Any dates the work must fit around
- Access details, including height
- Rough lengths or quantities, or drawings if you have them
- The product your specification calls for
The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or email drawings and photos to discuss it first.
