What happens on the day
The work is kept neat and contained to the joints we’re treating. Expect the work to take anything from a few hours to several days, depending on the number of plots. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can

About our new build mastic in Hamnavoe
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on bathrooms & en suites, kitchens and plot handovers, and people most often call us about sealant that never bonded to the surface and new-build shower sealant that has already split.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. In older homes, timber floors move through the year too.
You get a one-year guarantee, the same in Hamnavoe as everywhere else we work.

- Working hours on commercial sites
- Which sealant suits the joint
- How many areas need sealing
- Whether old sealant or filler has to be cut out
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- Any previous sealing or DIY work

Common questions in Hamnavoe
Is new build mastic in Hamnavoe guaranteed?
All our work, in Hamnavoe and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Will you come out to Hamnavoe?
Yes, Hamnavoe is covered. We work across all of Scotland, islands included, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels in Hamnavoe.
Are you insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. If something isn’t sealant, we will say so.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

New homes and floors in Hamnavoe
Hamnavoe is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
In and around Hamnavoe, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. Whether the job is in Hamnavoe itself or nearby, the right material for each joint matters as much as a neat finish.
Hamnavoe is in the Shetland Islands. Hamnavoe gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Hamnavoe is one of 63 places in the Shetland Islands where we work for new build mastic.

Why it’s worth doing now in Hamnavoe
The builder is generally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Around Hamnavoe, water from a failed joint in an older stone home can soak into timber and plaster.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
