For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. Typical jobs include cracks appearing as a new home settles and sealant applied over dusty or wet surfaces, on windows & doors, kitchens and skirting & floors.

Common questions in Puddle Dock
Can you do new build mastic in Puddle Dock?
Yes. Our work covers London and the South East, and Puddle Dock is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Do you work for landlords with property near Upminster station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Should I wait before resealing?
Where water is getting through, don’t wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
Can you match the sealant colour to my new kitchen or bathroom?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
My new home is still under warranty. Should I contact you?
Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Where do you work from?
Mr Mastic is based in Crawley. We cover Puddle Dock and the rest of Greater London, along with the rest of our area.
Can you reseal over the builder’s sealant?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
Can I do it myself?
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.
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.
What we do, step by step
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Puddle Dock. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- 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.
- Each bead is tooled and the cure times explained.
Before we arrive
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts

New build mastic around Puddle Dock
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
Puddle Dock is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you’ve bought a new home near Upminster station, the sealant around baths, showers and frames is worth checking in the first year or two.

How we quote for new build mastic
We quote each job individually. This is what makes a difference:
- Whether there’s mould to deal with
- The type of sealant required
- How easy the joints are to reach
- The number of rooms or windows
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
What to tell us when you ask for a quote:
- The problem you’ve noticed
- Access, such as stairs, a lift or height
- The type of property
- If someone has resealed it before
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, call 0345 464 0079 or email us.
Why it’s worth doing now in Puddle Dock
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times for the lot. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Why book with us
- Over 20 years’ experience
- A choice of colours where the product allows
- Colour agreed with you before any work starts
- An ARBOMaster approved applicator

When something else is needed
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Cracking that points to a structural problem
- Leaking fittings rather than failed sealant
- Disputes or warranty claims with your builder
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before booking.
