I let a flat near Ewell West station. Can you help?

Can you work from my snagging list?

How much does new build mastic cost in Ewell?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
My new home is still under warranty. Should I contact you?
Your builder, if you’re still in their snagging or warranty period. If that doesn’t work out, we are happy to quote with our 12-month guarantee.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
How we handle new build mastic in Ewell
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. Typical jobs include cracked sealant around new window and door frames and sealant applied over dusty or wet surfaces, across plot handovers, kitchens and show homes.
In a town like Ewell, older houses sit alongside newer estates. In a newer home, sealant and floor joints are normally among the first things to need attention.
Big or small, it’s backed by our 12-month guarantee.

Aftercare tips
So the new joints stay in good condition:
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
- Record problems with dated pictures
- Check bath and shower seals every few months as the house settles
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.

What else we do in Ewell
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What affects the quote in Ewell
Your quote is based on your job. We take into account:
- How many rooms, windows or areas are involved
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- The number and length of the joints
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Any access issues, like height or stairs
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
- A few pictures by email, if you can
If you’re in Ewell and need new build mastic, phone 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
Why deal with it now?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and they’re far easier to fix early.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

The process
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. A visit in Ewell needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Before we arrive
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
