New homes and floors in Cippenham
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Burnham station, it’s worth checking the sealant early, while snags are still fresh. In and around Cippenham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

About our new build mastic in Cippenham
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks rather than sitting on a layer of grit. If you have new-build shower sealant that has already split and gaps opening as the house dries out and settles, we can put it right.
For a new home in or near Cippenham, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
You get a one-year guarantee, the same in Cippenham as everywhere else we work.

What we cannot put right
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Cracked trays, tiles or worktops
- Movement caused by a poorly fitted tray or bath
- Leaking fittings rather than failed sealant
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Ventilate bathrooms well, especially in the first year
- Act quickly if a seal starts to leak
- Look at the sealant regularly in the first couple of years
- Photograph failed sealant before it’s redone
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you, so raise it early.

Landlord and commercial work in Cippenham
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
What we do, step by step
The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we tell you how long to leave it before we go. Parking around Cippenham is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can

Advice
Cippenham questions
I let a flat near Burnham station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you cover smaller places like Cippenham?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Why has my new-build shower seal failed already?
It’s common, and there are generally two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
When is the best time to reseal in a new build?
Any seal that’s leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
How the job changes by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. We will plan around viewing times.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Why act early in Cippenham
The builder is usually the first port of call while the snagging or warranty period runs. If it keeps failing or isn’t dealt with, we can reseal it properly. In an older home around Cippenham, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
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 play a part.
Why choose Mr Mastic in Cippenham
- Rated 4.9 stars on Google
- Quality sealants from Arbo and Everbuild
- 20+ years of sealant experience
- Every job guaranteed for a year
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
