How we handle new build mastic in Aldermaston
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We work on skirting & floors, bathrooms & en suites and plot handovers, and common reasons people get in touch are frame joints opening as the plaster dries and worktop and upstand sealant coming away.
Around Aldermaston, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
All our work is covered by our 12-month guarantee, wherever you are in West Berkshire.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Put sealant faults on your snagging list early
- Keep water off fresh sealant until it has cured
- Look at the sealant regularly in the first couple of years
- Photograph failed sealant before it’s redone
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The product the joint needs
- Any working-time requirements on site
- Access and height
- The size of the job
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
What to tell us for a quote
Before you ask for a quote, have a think about:
- The type of property
- Any access issues, like height or stairs
- If someone has resealed it before
- How many joints, rooms or windows are involved
To get a quote, call 0345 464 0079 or drop us an email with the location and a short description of the problem. You’ll have a clear quote before work begins.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How it works
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours in a single home in most cases. Somewhere as small as Aldermaston, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- On commercial sites, let us know about site rules

Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Older cottages and farmhouses around Aldermaston can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- Full insurance on every job
- Trusted Arbo and Everbuild sealants
- Neat joints and a tidy finish
- A sealant colour to suit the surroundings

Different surfaces, different methods
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Plot handovers
