Isington questions
Do you work for landlords with property near Bentley (Hampshire) station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Isington?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before any work starts.
Do you work for developers?
Yes. We work through plots to your schedule, room by room. Tell us the plots and the joints involved and we’ll quote.
What information do you need?
A short description and the location. We will ask anything else we need to know.
New build mastic in Isington, done properly

Common call-outs are for sealant work across a run of new homes and leaking shower tray seals in a new home, on skirting & floors, kitchens and windows & doors.
For a small place like Isington, the journey and access are planned in advance, and once on site, the job is the same as anywhere.

What affects the quote in Isington
We do not publish a price list. What we look at:
- How many rooms, windows or areas are involved
- Whether the work is at height
- The amount of work
- Which sealant suits the joint
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- Roughly how big the job is
- Access, such as stairs, a lift or height
- A few pictures by email, if you can
- The problem you’ve noticed
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work and give you a clear quote.
Joints and finishes in Isington homes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

When to call us in Isington
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
The problems people normally mention when they call are:
- Joints pulling apart as timber shrinks
- Kitchen sealant that has pulled off the wall
- Internal frame sealant that has split
- Sealant work across a run of new homes
Around Isington, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- How long to leave it before use
- The length of the guarantee
- Whether you can choose the colour
- How the joint is cleaned and prepared
How it works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. It usually takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Isington, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks

Advice
How the job changes by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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.
Aftercare tips
Aftercare is simple:
- Wait for the cure time before using a resealed shower
- Act quickly if a seal starts to leak
- Report sealant problems to your builder during the snagging period
- Look at the sealant regularly in the first couple of years
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
