New Build Mastic in Alfold Crossways
We cover Alfold Crossways for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.

- Gaps behind new kitchen upstands

New build mastic in Alfold Crossways
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. If you are dealing with new-build shower sealant that has already split and worktop and upstand sealant coming away, we can help.
Around Alfold Crossways, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Every job is covered by a 12-month guarantee, wherever you are in Surrey.

Alfold Crossways questions
Will you come out to Alfold Crossways?
Yes, Alfold Crossways is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Alfold Crossways for new build mastic?
Yes. We work across London and the South East, and Alfold Crossways is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
My new home is still under warranty. Should I contact you?
Start with your builder while their snagging or warranty period runs. If that does not work out, we are happy to quote with our one-year guarantee.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before we start.
Can you reseal over the builder’s sealant?
No. New silicone will not bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.
Is there a guarantee?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
Should I wait before resealing?
Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.
Landlords, agents and businesses in Alfold Crossways
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Housing providers, facilities teams and property managers book us too in Alfold Crossways and across Surrey. We can quote a run of properties together, and we are fully insured.
Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times to plan around. Where a wall is exposed, as many are in small places like Alfold Crossways, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.

The cost reflects the work involved, not guesswork. That is why we ask about the job first.

What new build mastic looks like in Alfold Crossways
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

What the job involves on each surface
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
When to call us in Alfold Crossways
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
The most common problems we see are:
- Internal frame sealant that has split
- Second-fix sealing on new plots
- Cracks appearing as a new home settles
- New-build shower sealant that has already split
Around Alfold Crossways, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote
- Which colour the sealant will be
- Is the old sealant removed completely?
- Which sealant they’ll use, and why
- What the quote includes, VAT included or not
The process
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours in a single home. For a village or hamlet like Alfold Crossways, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we are working on
How to get a quote
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll take it from there.
