DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
New build mastic in Cornish Hall End, done properly
Across Cornish Hall End, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. We’re often asked to deal with cracked sealant around new window and door frames and gaps behind new kitchen upstands, on windows & doors, skirting & floors and plot handovers.
Older homes in small places like Cornish Hall End often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Do you need new build mastic in Cornish Hall End?
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
Look out for these signs:
- Sealant that never bonded to the surface
- Messy sealant that spoils new finishes
- Worktop and upstand sealant coming away
- Skirting joints opening in the first winter
For jobs in and around Cornish Hall End, choosing the right material for each joint is as important as a tidy finish.

Advice
When it is not the sealant
New sealant can’t fix everything, and we will tell you before we start. It won’t solve:
- Damaged fittings that need replacing
- Plumbing faults behind the sealant
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
Surfaces we seal
- Skirting & floors
- Kitchens
- Windows & doors
- Show homes
- Bathrooms & en suites
- Plot handovers
What the job involves on each surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk.
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there suited to the job.

Quotes for new build mastic in Cornish Hall End
We quote each job individually. These are the things that affect it:
- Working hours on commercial sites

You do not need to know the technical terms. It helps if you can tell us:
- How we’d reach the joints
- Whether it’s a home or a business
- If someone has resealed it before
- Photos by email, if that’s easy
Every job is quoted individually, so start by telling us what you need. Just call 0345 464 0079 or send us an email with the details.
Common questions in Cornish Hall End
Is there a guarantee on new build mastic in Cornish Hall End?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover Cornish Hall End for new build mastic?
Yes, Cornish Hall End is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing.
How long before the joint can be used?
It depends on the product. We tell you how long to leave it before we go.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
Can you do several jobs on one visit?
Yes. Just list everything you need and you will get one quote.
Can I send you my snagging list?
Yes. Snagging lists are a common starting point for us. We’ll go through the sealant items and agree what we will do.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can you match the sealant colour to my new kitchen or bathroom?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Wipe joints with warm soapy water
- Act quickly if a seal starts to leak
- Watch for new gaps as the house dries out
- Follow the cure time we give you
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left in a busy bathroom.
