Questions from Gordon
Is new build mastic in Gordon guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Is Gordon in your area for new build mastic?
Yes. We work across all of Scotland, and Gordon is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Why does sealant fail so quickly in new builds?
There are usually two causes: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
Should I wait before resealing?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
New build mastic in Gordon, done properly
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly rather than sitting on a layer of grit. Common call-outs are for leaking shower tray seals in a new home and frame joints opening as the plaster dries, across kitchens, show homes and skirting & floors.
Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Each job carries a 12-month guarantee, whatever its size.

Aftercare tips
After the cure time, these simple habits help:
- Photograph failed sealant before it’s redone
- Avoid scourers and strong chemicals on sealant
- Open a window or run the fan after bathing
- Do not wait for the house to settle if water is getting through
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
If you manage several properties in or around Gordon, several properties can go on one quote. Send us the addresses and the work at each, and photos by email help.
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. 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 Gordon depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Different surfaces, different methods
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first.

Leave it or put it right?
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 an older home around Gordon, damp from a failed joint can get into timber and plaster.
Every job is a little different, so each one gets its own quote. 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.

In and around Gordon, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. Whether the job is in Gordon itself or nearby, the right material for each joint matters as much as a neat finish.

What sealant work can’t fix
Sealant is not the answer to every problem, and we will tell you before any work starts. Sealant will not put right:
- Leaking fittings rather than failed sealant
- Deciding who is responsible under a builder’s warranty
- Damaged fittings that need replacing
