How we handle new build mastic in Burnham
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We work on kitchens, bathrooms & en suites and show homes, and common reasons people get in touch are cracked sealant around new window and door frames and beads laid onto grit and dust from the build.
In and around Burnham, floors range from older timber boards to tiles and newer finishes, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
Big or small, it’s backed by our 12-month guarantee.

Should I try it myself first?
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 does not work out, we can still put it right.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Your questions about new build mastic in Burnham
I let a flat near Burnham station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Do you cover Burnham for new build mastic?
Yes, Burnham is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job.
How long does the job take?
As a guide, most jobs take anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer.
Do you have insurance?
Yes. We’re fully insured.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Surface by surface
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and prime where the product needs it.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out and baths are filled before sealing.
What happens on the day
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the number of plots. For a job in Burnham, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Tell us about any water getting in
- Mention if the joints have been sealed before
- Move anything stored near the joints

Signs you need new build mastic in Burnham
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
Any of these means the joints need attention:
- Messy sealant that spoils new finishes
- Skirting joints opening in the first winter
- Worktop and upstand sealant coming away
- Gaps opening as the house dries out and settles
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.
What your quote should include
- Whether the sealant suits the joint
- What preparation is included
- Whether they seal over old material or remove it
- What insurance they hold
What affects the cost of new build mastic
Jobs vary more than people expect. What affects the quote:
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
- Access and height
- How much old sealant there is and how hard it is to remove
What you pay reflects the work, not guesswork. That is why we ask a few questions first.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- Whether it has been sealed before
- What’s wrong with the joints now
- How we’d reach the joints
- Where the job is, and your postcode
We quote each job on its own. Simply ring 0345 464 0079 or send us an email and describe the job, and photos are welcome.

What else we do in Burnham
What new build mastic looks like in Burnham
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.
Around Burnham, as everywhere, new build mastic is only as good as the preparation behind it.
Burnham is about 2 miles north-west of Slough, in Slough. We provide new build mastic to homes and businesses in Burnham and nearby, as part of our work across Slough. Burnham is one of 31 places in Slough where we work for new build mastic. We also work in Reading, about 15 miles from Burnham.
We cover every part of SL1, SL6 and SL2 for new build mastic. If you need new build mastic at a property on Stomp Road, Priory Road and High Street or a nearby road, our applicators can take on the job. Nearby, we also carry out new build mastic in Huntercombe (1 mile south), Hitchambury (1 mile west), Taplow (1 mile west), Cippenham (1 mile south-east) and Rose Hill (1 mile north-west). Further out, we also cover Chalvey (3 miles south-east), Langley (5 miles east), Upton (3 miles south-east), Datchet (5 miles south-east), Stoke Poges (3 miles east) and Ditton (5 miles south-east).

Around Burnham
Typical jobs here are in homes near Haymill Valley, Garibaldi Public House and Our Lady of Peace Catholic Primary and Nursery School, among other places. Burnham’s nearest station is Burnham station, about 0.7 miles south-east of the centre. Other landmarks nearby include The Reitlinger Bequest Museum (1.9 miles west) and Windsor Castle (4 miles south-east). Not far away are Burnham Beeches and Taplow Lake.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Record problems with dated photos
- Wait for the cure time before using a resealed shower
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
Why deal with it now?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Around Burnham, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
