New build mastic in Kelton Hill
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on windows & doors, bathrooms & en suites and show homes, and people most often call us about frame joints opening as the plaster dries and messy sealant that spoils new finishes.
Work in a place like Kelton Hill is planned ahead, journey included. 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 email us at info@mrmastic.co.uk.

What affects the quote in Kelton Hill
Your quote is based on your job. We take into account:
- The size of the job
- Which sealant suits the joint
- How many rooms, windows or areas are involved
- When we can work, for business premises
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Whether it has been sealed before
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
What happens if it’s left?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Leaving a failed joint usually makes the job bigger, not smaller. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.
What you get with us
- More than 20 years in sealant work
- A choice of colours where the product allows
- Tidy, careful work
- 12-month guarantee on every job
When it is not the sealant
New sealant can’t fix everything, and we will tell you before we start. Sealant will not put right:
- Disputes or warranty claims with your builder
- Baths and trays that move too much for sealant to cope with
- Leaking fittings rather than failed sealant
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.
What we seal
- Skirting & floors
- Kitchens
- Windows & doors
- Bathrooms & en suites
- Show homes
- Plot handovers
When to call us in Kelton Hill
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
Common reasons people contact us include:
- Untidy sealant flagged on a snagging list
- Worktop and upstand sealant coming away
- Second-fix sealing on new plots
- Internal frame sealant that has split
Whether the job is in Kelton Hill itself or nearby, the right material for each joint matters as much as a neat finish.
What your quote should include
- When the joint can take water or movement
- How long the guarantee is
- Are they insured?
- Whether they seal over old material or remove it

Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme, room by room. Tell us the plots and the joints involved and we will quote.
Why does sealant fail so quickly in new builds?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Where are you based?

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours for most snagging lists, longer for a run of plots. Around Kelton Hill, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on
