New Build Mastic in Chertsey
Professional new build mastic in and around Chertsey, with old sealant always removed completely and a one-year guarantee.
- Kitchen sealant that has pulled off the wall
- Untidy sealant flagged on a snagging list
- Shower seals failing in the first year or two
When it isn’t the sealant
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Movement caused by a poorly fitted tray or bath
- Deciding who is responsible under a builder’s warranty
- Cracking that points to a structural problem
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
Surfaces we seal
- Skirting & floors
- Bathrooms & en suites
- Windows & doors
- Show homes
- Plot handovers
- Kitchens
New build mastic in Chertsey
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. Common call-outs are for shower seals failing in the first year or two and gaps between new skirting and floors, across skirting & floors, show homes and plot handovers.
Where new homes go up in smaller places like Chertsey, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

DIY sealant or a professional job?
If you do try it yourself, take your time over the 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.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

How we quote for new build mastic
The price is agreed before any work begins. It’s based on:
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
Asking for a quote
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- What’s wrong with the joints now
- The address or postcode of the job
- Whether it’s a home or a business
We do not publish a price list. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or email us.
What happens if it’s left?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot and most come down to preparation. In a smaller place like Chertsey, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Parking around Chertsey is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky
