Questions from Hawkhurst
Do you work for landlords with property near Etchingham station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Do you cover Hawkhurst for new build mastic?
Yes, Hawkhurst is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Is there a guarantee?
Yes. Every job comes with a one-year guarantee.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
New build mastic in Hawkhurst
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly. If you have cracks appearing as a new home settles and internal frame sealant that has split, we can help.
In smaller places like Hawkhurst, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
There’s a 12-month guarantee on every job, large or small.

We also work for property managers and facilities teams in Hawkhurst and across Kent. Several sites can go on one quote, and we’re fully insured.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Do not wait for the house to settle if water is getting through
- Avoid running a DIY bead over the old one
- Keep photos and emails about snagging items
- Open a window or run the fan after bathing
Follow the cure time we give you before the area gets wet. Most silicones need around a day before water reaches them.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
Surface by surface
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens, food-safe where it’s needed.
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.
When to call us in Hawkhurst
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry before the sealant goes on.
These are the problems we’re asked about most:
- Sealant work across a run of new homes
- Cracked caulk along new skirting
- Frame joints opening as the plaster dries
- New-build shower sealant that has already split
If you’ve bought a new home near Etchingham station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- Whether the sealant suits the joint
- How the surfaces are prepared before sealing
- Who turns up on the day

What new build mastic looks like in Hawkhurst
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.

The process
At the end, we look at the finished work together. The work normally takes a few hours in a single home, depending on how much there is to do. In a smaller place like Hawkhurst, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot and most come down to preparation. In a smaller place like Hawkhurst, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
