About our new build mastic in East Burnham
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you have sealant that never bonded to the surface and plot mastic for developers ahead of handover, we can put it right, on show homes, windows & doors and bathrooms & en suites alike.
Work in a small place like East Burnham just needs the journey and access planning, and the work itself is the same as on any site.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Why act early in East Burnham
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot. In a small place like East Burnham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

East Burnham questions
Will you come out to East Burnham?
Yes, East Burnham is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Burnham station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Is it normal for sealant to crack in a new home?
There are generally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Do you guarantee your work?
Yes. Every job comes with a 12-month guarantee.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.

New build mastic in East Burnham: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around East Burnham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
East Burnham is about 2 miles north of Slough, in Slough. We carry out new build mastic for homeowners, landlords and businesses in East Burnham. Our area takes in 31 places across Slough. Reading is on our list too, about 17 miles from East Burnham.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Ventilate bathrooms well, especially in the first year
- Watch for new gaps as the house dries out
- Photograph failed sealant before it’s redone
- Wipe joints with warm soapy water
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
Common problems we fix in East Burnham
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
Any of these means the joints need attention:
- Gaps between new skirting and floors
- Internal frame sealant that has split
- Untidy sealant flagged on a snagging list
- Second-fix sealing on new plots
If you’ve bought a new home near Burnham station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before you book
- How much experience the applicator has
- Whether they seal over old material or remove it
- What product goes in the joint
- How long to leave it before use
What affects the quote in East Burnham
Some jobs are bigger than they look, and some smaller. The main factors:
- Any working-time requirements on site
- The size of the job
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Any access issues, like height or stairs
- A few photos by email, if you can
- The address or postcode of the job
- How many joints, rooms or windows are involved

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
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.
For landlords and businesses
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
