Doing it in-house
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Mastic sealing in Sandwick
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Communal entrances and stairs stay usable while we work. We work on window and door perimeters on blocks, communal kitchens and washrooms and communal entrances and stairwells, and what we’re called in for most is damp patches beside frames and a mix of products and colours from past repairs. Most enquiries from Sandwick start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
In smaller Scottish places like Sandwick, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Frames on exposed elevations are where mastic typically fails first.
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.

Advice
Cost factors for mastic joints
These are the things that shape the price:
- Travel to remote or island sites
- Phasing around occupants
- Access and working height
- How much existing material needs removing
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- The product your specification calls for
- The site address and postcode
- A wide shot and a close-up of the area
- Approximate linear metres or a joint schedule
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or email drawings and photos to discuss it first.

What else we do in Sandwick
Questions we are asked in Sandwick
Will you travel to Sandwick on the island?
Yes. We work across every Scottish council area, and that includes island locations such as Sandwick. Ferry times and the weather set the plan, so we ask for photographs and a full list first.
Do you take on block-wide or estate-wide mastic work in Sandwick?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photographs and we will give a fixed quote.
How do you handle work on occupied blocks?
We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
Commercial clients in Sandwick
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Sandwick can sit alongside others in a wider programme across the Shetland Islands.
Why act early in Sandwick
Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes and those cost far more to put right. Renewing every failing joint on one visit is the sensible approach for a place like Sandwick. Photos of each area help us quote the whole job.
Pricing mastic joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

- Joints cleaned back to sound surfaces
- Constructionline member for supplier checks
- Clear, fixed quotes

After the work
A few simple habits keep the new joints working:
- Share your contractor requirements early
- Encourage occupiers to report problems at frames
- Keep a record of when each building was resealed
- Check the asbestos register before any old mastic is disturbed
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
