Different surfaces, different methods
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. Tell us when the home is open so we can plan around it.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk in a colour to suit.
New build mastic in Bentworth
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. If you have sealant applied over dusty or wet surfaces and new-build shower sealant that has already split, we can help.
Somewhere as small as Bentworth, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most snagging lists, longer for a run of plots. In a small place like Bentworth, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
- Let us know about parking restrictions
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
Related advice
Work for landlords, hotels and businesses
Landlords and letting agents in Bentworth can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times to plan around. In a small place like Bentworth, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
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 make a difference.

Your questions about new build mastic in Bentworth
Do you cover Bentworth for new build mastic?
Yes, Bentworth is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
I let a flat near Alton station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Should I wait before resealing?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
Do you work for developers?
Yes. We work through plots to your schedule ready for handover. Get in touch with the number of plots and the scope for a clear quote.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
What colour sealant will you use?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before any work starts.
Why has my new-build shower seal failed already?
It’s common, and there are generally two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
When it isn’t the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Baths and trays that move too much for sealant to cope with
- Damaged fittings that need replacing
- Leaking fittings rather than failed sealant
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Look at the sealant regularly in the first couple of years
- Wipe joints with warm soapy water
- Raise failed sealant with the developer while you are covered
- Ventilate bathrooms well, especially in the first year
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
