What the job involves on each surface
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
New build mastic in Witley, done properly
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks rather than sitting on a layer of grit. We work on bathrooms & en suites, windows & doors and skirting & floors, and common reasons people get in touch are cracks appearing as a new home settles and plot mastic for developers ahead of handover.
Older homes in small places like Witley often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work is covered by a one-year guarantee.

What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Disputes or warranty claims with your builder
- Leaking fittings rather than failed sealant
- A tray or bath that is not properly supported, until it’s fixed
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
Surfaces we seal
- Kitchens
- Plot handovers
- Bathrooms & en suites

- Skirting & floors
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Photograph failed sealant before it’s redone
- Use the extractor fan every time you shower
- Don’t seal over failed sealant yourself
- Clean sealant with mild detergent, not abrasives
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a few hours in a single home, depending on the amount of work. Somewhere like Witley needs a little journey planning: let us know about lanes, gates and parking. 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.
- We remove the failed sealant and clean the joints.
- 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.
Getting ready for the visit

When to call us in Witley
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
These are the problems we’re asked about most:
- Cracks appearing as a new home settles
- Sealant applied over dusty or wet surfaces
- Internal frame sealant that has split
- Leaking shower tray seals in a new home
If you’ve bought a new home near Milford (Surrey) station, the sealant around baths, showers and frames is worth checking in the first year or two.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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.
Landlord and commercial work in Witley
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
