For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
Landlords and letting agents in Sheerwater can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for.
New build mastic in Sheerwater
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. Typical jobs include sealant applied over dusty or wet surfaces and untidy sealant flagged on a snagging list, across kitchens, skirting & floors and plot handovers.
Older homes in small places like Sheerwater often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Our work is backed for twelve months, in Sheerwater and everywhere else we cover.

What we’re called out for in Sheerwater
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.
It’s worth asking for a quote if you see:
- Cracks appearing as a new home settles
- Plot mastic for developers ahead of handover
- Leaking shower tray seals in a new home
- Gaps behind new kitchen upstands
If you’ve bought a new home near West Byfleet station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before booking anyone
- Is the old sealant removed completely?
- Who does the work, and how experienced they are
- How the surfaces are prepared before sealing
- Is VAT in the price?
Surface by surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing so the sealant lasts.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Sheerwater questions
Can you help a landlord with a rental near West Byfleet station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Is Sheerwater within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What do you need from me for a quote?
Tell us what needs doing and where. If we need more, we’ll ask.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Do you use white or clear sealant?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
What sealant work can’t fix
We’ll always be straight with you, so here’s what sealant can’t fix:
- Your warranty claim itself, which is between you and the builder
- Broken tiles or a split tray
- A tray or bath that is not properly supported, until it’s fixed
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal

Why deal with it now?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. You get one visit and one clear quote for the lot. Older cottages and farmhouses around Sheerwater can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why us?
- An ARBOMaster approved applicator
- 20+ years of sealant experience
- A choice of colours where the product allows
- You choose the colour before work begins

The process
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Sheerwater, the journey is planned in advance: 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 start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- Clear items away from the joints we are working on
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

What affects the cost of new build mastic
Every job gets its own quote. This is what makes a difference:
- Whether the work is at height
- The number of rooms or windows
- Mould in or behind the old joints
- The old material and how stubborn it is
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
Asking for a quote
To make quoting easier, please include:
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- Pictures of the joints, sent by email
- Where the property is
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
