How we handle new build mastic in South Dell
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that’s what rushed new-build sealant generally lacks. Typical jobs include leaking shower tray seals in a new home and internal frame sealant that has split, on kitchens, show homes and skirting & floors.
Work in a place like South Dell is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Your job is guaranteed for a year, as with all our work.

Your questions about new build mastic in South Dell
Is South Dell within the area you cover?
Yes, we do. We work across all of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover South Dell for new build mastic?
Yes. Our work covers the whole of Scotland, and South Dell is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Can you work from my snagging list?
Yes. Send it with pictures and we’ll quote for the sealant items. If something isn’t sealant, we will say so.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
How the job changes by surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish ready for viewings. We will plan around viewing times.
Joints and finishes in South Dell homes
South Dell 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. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
In and around South Dell, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes anything from a few hours to several days, depending on the number of plots. Around South Dell, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- 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.
Getting ready for the visit
- Clear the area around the work
- Let us know about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks

Advice
What we are called out for in South Dell
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Common reasons people contact us include:
- Kitchen sealant that has pulled off the wall
- Cracked caulk along new skirting
- Leaking shower tray seals in a new home
- Plot mastic for developers ahead of handover
Whether the job is in South Dell itself or nearby, the right material for each joint matters as much as a neat finish.

What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Disputes or warranty claims with your builder
- Movement caused by a poorly fitted tray or bath
- Broken tiles or a split tray
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.

For landlords and businesses
Landlords and letting agents in South Dell can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
What happens if it’s left?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a place like South Dell, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

How to look after the new joints
Aftercare is simple:
- Clean sealant with mild detergent, not abrasives
- Ventilate bathrooms well, especially in the first year
- Follow the cure time we give you
- Photograph failed sealant before it’s redone
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.
