Surface by surface
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
How we handle new build mastic in Lympne
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a seal that is letting water through needs doing now. We work on skirting & floors, bathrooms & en suites and show homes, and the jobs we see most are gaps opening as the house dries out and settles and beads laid onto grit and dust from the build.
Work in a small place like Lympne just needs the journey and access planning, and the work itself is the same as on any site.
Your job is guaranteed for a year, as with all our work.

Lympne questions
Do you work for landlords with property near Westenhanger station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Do you cover smaller places like Lympne?
Yes. Lympne is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before any work starts.
Do you work through snagging lists?
Yes. Snagging lists are a common starting point for us. We will go through the sealant items and agree what we’ll do.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.

What else we do in Lympne
The process
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work normally takes anything from a few hours to several days, depending on the number of plots. In a small place like Lympne, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- 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.
- We check every joint and tell you how long each needs to cure.
How to prepare
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we’re working on
- Mention any parking rules near the property

What affects the cost of new build mastic
The price is agreed before any work begins. It’s based on:
- The old material and how stubborn it is
- Whether there’s mould to deal with
- The size of the job
- When we can work, for business premises
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- If someone has resealed it before
- How we’d reach the joints
- How many joints, rooms or windows are involved
For new build mastic in Lympne, phone 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.

Do you need new build mastic in Lympne?
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Any of these means the joints need attention:
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
- Sealant applied over dusty or wet surfaces
- Frame joints opening as the plaster dries
If you’ve bought a new home near Westenhanger station, the sealant around baths, showers and frames is worth checking in the first year or two.
What to look for in a quote
- How the surfaces are prepared before sealing
- Is VAT in the price?
- The length of the guarantee
- How much experience the applicator has
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. Around Lympne, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
What you get with us
- Neat joints and a tidy finish
- 20+ years of sealant experience
- We never seal over old sealant
- Full insurance on every job
What new build mastic looks like in Lympne
Lympne is within about 2 miles of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
