New build mastic in Wavendon
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. We work on skirting & floors, show homes and windows & doors, and the jobs we see most are smeared, uneven beads picked up at snagging and cracked sealant around new window and door frames.
Around Wavendon, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Your job is guaranteed for a year, as with all our work.

How the visit works
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours in a single home.

- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- 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
- Mention if the joints have been sealed before

Why deal with it now?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Around Wavendon, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
Why us?
- An ARBOMaster approved applicator
- Sealant colour chosen to suit
- We never seal over old sealant
- You choose the colour before work begins

Your questions about new build mastic in Wavendon
Do you work for landlords with property near Woburn Sands station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Will you come out to Wavendon?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Wavendon, along with the rest of our area.
Do you work for developers?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours in a single home. We will give you a better idea when we quote.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Use the extractor fan every time you shower
- Wait for the cure time before using a resealed shower
- Do not wait for the house to settle if water is getting through
- Watch for new gaps as the house dries out
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
Joints and finishes in Wavendon homes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Wavendon, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What’s near Wavendon
In Wavendon, that means homes and buildings near The Stables pub and Walton High, among other places. Wavendon’s nearest station is Woburn Sands station, roughly 0.9 miles south-east. A little further out are Rugemont Castle (3.7 miles east) and Central Milton Keynes Shopping Centre (3.7 miles west). For a walk, there’s Caldecotte Lake and Blue Lagoon Park.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Common problems we fix in Wavendon
Sealant applied onto damp surfaces does not bond well. On a busy site, joints are not always given time to dry before the sealant goes on.
Most people get in touch after spotting one of these:
- Joints pulling apart as timber shrinks
- Sealant that never bonded to the surface
- New-build shower sealant that has already split
- Messy sealant that spoils new finishes
If you’ve bought a new home near Woburn Sands station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- Is VAT in the price?
- Whether the sealant suits the joint
- Whether they’re fully insured
