Milton Keynes questions
Can you do new build mastic in Milton Keynes?
Yes, Milton Keynes is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Do you work for landlords with property near Milton Keynes Central station?
Yes. We work for letting agents and landlords as well as homeowners. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Why does sealant fail so quickly in new builds?
There are generally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
How long does the job take?
As a guide, most jobs take a few hours in a single home. Bigger jobs take longer.
Can I send you my snagging list?
Yes. Send it with pictures and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Milton Keynes, along with the rest of our area.
New build mastic for homes and businesses in Milton Keynes
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We’re often asked to deal with skirting joints opening in the first winter and sealant work across a run of new homes, across skirting & floors, plot handovers and windows & doors.
Milton Keynes has plenty of estates from recent decades, where the builder’s original sealant around baths, frames and skirtings may be due for replacing. Snagging and second-fix sealing are part of what we do for developers and new-home owners alike.

- Deciding who is responsible under a builder’s warranty
- Structural cracks in walls or ceilings
- Broken tiles or a split tray

Joints and finishes in Milton Keynes homes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Milton Keynes was built as one of England’s post-war new towns. Newer neighbourhoods have been added to Milton Keynes over the years. Newer homes need snagging; older ones need their joints renewing.
For new homes near Milton Keynes Central station, it’s worth checking the sealant early, while snags are still fresh. Around Milton Keynes, as everywhere, new build mastic is only as good as the preparation behind it.

Why deal with it now?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. For businesses in Milton Keynes, a room closed because of a leak or mould costs more than the sealant, so failing joints are best replaced on a planned basis.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

What the job involves on each surface

Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
What happens on the day
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job. In Milton Keynes, we work in everything from flats and family homes to offices and hotels. For each, it helps to know about access, parking and where the joints are.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on
- Mention any parking rules near the property
