About new build mastic in Windsor and Maidenhead
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on kitchens, show homes and skirting & floors, and common reasons people get in touch are new-build shower sealant that has already split and gaps between new skirting and floors.
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours in a single home.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.

Where we work in Windsor and Maidenhead
In Windsor and Maidenhead, new build mastic work takes in new homes, older houses and commercial units, from Maidenhead, Windsor and Boyn Hill to the quieter places in between. The common thread is movement: every joint has to allow for it.
The South East is one of the drier parts of the UK, though outside sealant still needs a dry, clean joint, so work across Windsor and Maidenhead is planned around the weather.
Maidenhead: If you’ve bought a new home near Maidenhead station, the sealant around baths, showers and frames is worth checking in the first year or two. Around Maidenhead, as everywhere, new build mastic is only as good as the preparation behind it.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How we quote for new build mastic
The price is agreed before any work begins. It takes into account:
- How many areas need sealing
- When we can work, for business premises
- The type of sealant required
- Mould in or behind the old joints
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- Roughly how big the job is
- Photos by email, if that’s easy
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or email us.
What sealant work can’t fix
Sealant isn’t the answer to every problem, and we’ll tell you before work begins. It will not solve:
- Leaks from pipes, valves or wastes, which need a plumber
- A tray or bath that is not properly supported, until it’s fixed
- Deciding who is responsible under a builder’s warranty
Common problems we fix in Windsor and Maidenhead
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.
Look out for these signs:
- Smeared, uneven beads picked up at snagging
- New-build shower sealant that has already split
- Beads laid onto grit and dust from the build
- Skirting joints opening in the first winter
Why deal with it now?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly.
What your quote should include
- What happens if the job turns out different
- What guarantee comes with the work
- What the cure time is
- How much experience the applicator has
