About our new build mastic in Shellow Bowells
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. We work on windows & doors, plot handovers and skirting & floors, and the jobs we see most are cracked sealant around new window and door frames and leaking shower tray seals in a new home.
Work in a small place like Shellow Bowells just needs the journey and access planning, and once on site, the job is the same as anywhere.
Whatever the size of the job, you get the same one-year guarantee in Shellow Bowells and across Essex.

Shellow Bowells: your questions answered
Is new build mastic in Shellow Bowells guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover Shellow Bowells for new build mastic?
Yes. We work across London and the South East, and Shellow Bowells is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
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.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
What do you need from me for a quote?
A short description and the location, with photos by email if possible. If we need more, we will ask.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Do you take on second-fix sealing for builders?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send the schedule and any specification and we’ll give you a quote.

Common problems we fix in Shellow Bowells
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Any of these means the joints need attention:
- Sealant work across a run of new homes
- Cracks appearing as a new home settles
- New-build shower sealant that has already split
- Messy sealant that spoils new finishes
Around Shellow Bowells, as everywhere, new build mastic is only as good as the preparation behind it.

Why it’s worth doing now in Shellow Bowells
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Around Shellow Bowells, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why book with us
- ARBOMaster approved applicator
- A choice of colours where the product allows

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. In a small place like Shellow Bowells, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Before we arrive
- Mention any parking rules near the property
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
