Aftercare tips
So the new joints stay in good condition:
- Check bath and shower seals every few months as the house settles
- Ventilate bathrooms well, especially in the first year
- Avoid scourers and strong chemicals on sealant
- Avoid running a DIY bead over the old one
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents, which can damage the surface.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
New build mastic for homes and businesses in Moor Park
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. We work on bathrooms & en suites, kitchens and skirting & floors, and people most often call us about shower seals failing in the first year or two and sealant applied over dusty or wet surfaces.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
Each job carries a 12-month guarantee.

New build mastic in Moor Park: local notes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Rickmansworth station, the sealant around baths, showers and frames is worth checking in the first year or two.

Questions from Moor Park
I let a flat near Rickmansworth station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Do you cover Moor Park for new build mastic?
Yes, Moor Park is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you’re covered. Once that’s done, or if they will not put it right, we can reseal it properly.
Is it worth resealing while the house is still settling?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
How long will you be here?
A typical job takes a few hours for most snagging lists, longer for a run of plots, including preparation and clearing up. We’ll confirm how long when we quote.
What we can’t put right
In fairness, there are a few things sealant will not fix:
- Settlement cracks that need a surveyor
- Damaged fittings that need replacing
- Baths and trays that move too much for sealant to cope with
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.
What to tell us for a quote
To make quoting easier, please include:
- Whether it has been sealed before
- The rough size of the job
- Any access issues, like height or stairs
- The address or postcode of the job

Surface by surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. We will plan around viewing times.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Common problems we fix in Moor Park
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Keep an eye out for these signs:
- Worktop and upstand sealant coming away
- Leaking shower tray seals in a new home
- Skirting joints opening in the first winter
- Smeared, uneven beads picked up at snagging
As a London address, Moor Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Questions to ask before you book
- Whether they seal over old material or remove it
- What insurance they hold
- Which sealant they’ll use, and why
- Which colour the sealant will be
What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most snagging lists, longer for a run of plots. In Moor Park, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts
