How we handle new build mastic in Hawthorn Hill
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. If you have sealant that never bonded to the surface and worktop and upstand sealant coming away, we can put it right.
Older homes in small places like Hawthorn Hill often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Your job is guaranteed for a year, as with all our work.

Honest limits
Sealant is not the answer to every problem, and we’ll tell you before work begins. It will not solve:
- Disputes or warranty claims with your builder
- Baths and trays that move too much for sealant to cope with
- Damaged fittings that need replacing

What we seal
- Plot handovers
- Skirting & floors
- Bathrooms & en suites
- Show homes
- Kitchens
- Windows & doors
Different surfaces, different methods
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
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.
Questions from Hawthorn Hill

Do you cover Hawthorn Hill for new build mastic?
Yes. We work across London and the South East, and Hawthorn Hill is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you work through snagging lists?
Yes. We often work straight from a snagging list. We will go through the sealant items and agree what we’ll do.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How to look after the new joints
To keep the joints looking good and working properly:
- Clean sealant with mild detergent, not abrasives
- Open a window or run the fan after bathing
- Wait for the cure time before using a resealed shower
- Don’t wait for the house to settle if water is getting through
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
Joints and finishes in Hawthorn Hill homes

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, 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.

Why act early in Hawthorn Hill
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. Where a wall is exposed, as many are in small places like Hawthorn Hill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Why us?
- Any old sealant cut out fully, not covered over
- Domestic, commercial and hotel work
- A 12-month guarantee on all work
- Anti-fungal silicone where joints get wet
