What the job involves on each surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
New build mastic for homes and businesses in Ness
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. Common call-outs are for untidy sealant flagged on a snagging list and joints pulling apart as timber shrinks, across bathrooms & en suites, kitchens and skirting & floors.
For a place like Ness, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
You are covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Common questions in Ness
Is there a guarantee on new build mastic in Ness?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Ness in your area for new build mastic?
Yes. We work across all of Scotland, and Ness is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Where is Mr Mastic based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Why has my new-build shower seal failed already?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
What new build mastic looks like in Ness
Ness is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
In and around Ness, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Ness is about 18 miles north of Stornoway, in Na h-Eileanan Siar. Ness gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Ness is one of 87 towns and villages in Na h-Eileanan Siar where we work.

Signs you need new build mastic in Ness
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Look out for these signs:
- Cracked sealant around new window and door frames
- Messy sealant that spoils new finishes
- Gaps between new skirting and floors
- Second-fix sealing on new plots
Whether the job is in Ness itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before booking
- How the colour is chosen
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
- What product goes in the joint
How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the number of plots and we leave things clean and tidy. Outdoor work around Ness depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Preparing for the visit
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed

Related advice
Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. In an older home around Ness, damp from a failed joint can get into timber and plaster.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Why choose Mr Mastic in Ness
- We leave the area clean and tidy
- Over 20 years’ experience
- A sealant colour to suit the surroundings
- Sanitary silicone with an anti-fungal additive in wet areas
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Wipe joints with warm soapy water
- Ventilate bathrooms well, especially in the first year
- Keep photos and emails about snagging items
- Put sealant faults on your snagging list early
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day before water reaches them.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
