Woburn Sands New Build Mastic
Problem with your new-build sealant joints in Woburn Sands? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Sealant work across a run of new homes
- Shower seals failing in the first year or two
- Messy sealant that spoils new finishes
How we handle new build mastic in Woburn Sands
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference. If you are dealing with cracks appearing as a new home settles and leaking shower tray seals in a new home, we can help, whatever the surface.
Where new homes go up in smaller places like Woburn Sands, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
We stand behind the work with a one-year guarantee.

The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the number of plots. For a job in Woburn Sands, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each joint is checked for movement before we start.
- 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.
Preparing for the visit
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive

Common questions in Woburn Sands
Is Woburn Sands in your area for new build mastic?
Yes, Woburn Sands is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.
Will you come out to Woburn Sands?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Do you work through snagging lists?
Yes. Send it with photos and we’ll quote for the sealant items. If something is not sealant, we will say so.
My new home is still under warranty. Should I contact you?
Your builder, if you are still in their snagging or warranty period. If that does not work out, we’re happy to quote.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Honest limits
In fairness, there are a few things sealant won’t fix:
- Settlement cracks that need a surveyor
- Cracked trays, tiles or worktops
- Deciding who is responsible under a builder’s warranty
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.

Why act early in Woburn Sands
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. Homes in smaller places like Woburn Sands can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.
Why book with us
- Quality sealants from Arbo and Everbuild
- We leave the area clean and tidy
- An ARBOMaster approved applicator
- White, clear, grey or another colour, product permitting

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Record problems with dated pictures
- Put sealant faults on your snagging list early
- Avoid scourers and strong chemicals on sealant
- Ventilate bathrooms well, especially in the first year
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
Early snagging is easier snagging. Small faults turn into leaks if left over time.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. 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.
