About our new build mastic in Gracemount
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you’re dealing with skirting joints opening in the first winter and beads laid onto grit and dust from the build, we can put it right, on skirting & floors, bathrooms & en suites and plot handovers alike.
Scotland’s cities are still adding new flats and houses, and in new homes, sealant and floor joints are often among the first snags.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

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. Dealing with it early keeps the damage away from ceilings, floors and finishes. Private landlords in Gracemount must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

How the job changes by surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there, food-safe where it’s needed.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clean sealant with mild detergent, not abrasives
- Look at the sealant regularly in the first couple of years
- Use the extractor fan every time you shower
- Raise failed sealant with the developer while you are covered
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
FAQs for Gracemount
What guarantee comes with new build mastic in Gracemount?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can you help a landlord with a rental near Shawfair station?
Yes. We work for landlords and agents as well as householders. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Gracemount.
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.
What colour sealant will you use?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We’ll agree it with you first.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours in a single home. We will give you a better idea when we quote.
What does new build mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, email us at info@mrmastic.co.uk with a short description of the job.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
What we’re called out for in Gracemount
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly.
It’s worth asking for a quote if you see:
- Cracks appearing as a new home settles
- New-build shower sealant that has already split
- Skirting joints opening in the first winter
- Messy sealant that spoils new finishes
In and around Gracemount, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- When the joint can take water or movement
- Is VAT in the price?
- How the colour is chosen
- Are they insured?
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What affects the cost of new build mastic
Jobs vary more than people expect. The main factors:
- How many areas need sealing
- Any working-time requirements on site
- How easy the joints are to reach
- The old material and how stubborn it is
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
We don’t publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, send an email to info@mrmastic.co.uk.
What we do, step by step
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of plots for a typical job. For a tenement in Gracemount, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
