New build mastic for homes and businesses in Upton Park
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first, and if it isn’t put right, get in touch with us. Common call-outs are for new-build shower sealant that has already split and worktop and upstand sealant coming away, across windows & doors, skirting & floors and bathrooms & en suites.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
We stand behind the work with a 12-month guarantee.

Joints and finishes in Upton Park homes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
If you’ve bought a new home near Woodgrange Park station, the sealant around baths, showers and frames is worth checking in the first year or two.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

How we quote for new build mastic
You’ll get a clear quote before work begins. It’s based on:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- Any mould that needs treating
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
What to tell us when you ask for a quote:
- The problem you’ve noticed
- A few photos by email, if you can
- The type of property
- The address or postcode of the job
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
What we are called out for in Upton Park
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
The problems people normally mention when they call are:
- Worktop and upstand sealant coming away
- Beads laid onto grit and dust from the build
- Second-fix sealing on new plots
- Gaps between new skirting and floors
As a London address, Upton Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Why it’s worth doing now in Upton Park
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Upton Park, the repair is bigger than a sealant job.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
What you get with us
- Over 20 years’ experience
- Sanitary silicone with an anti-fungal additive in wet areas
- Sealant colour chosen to suit
- We never seal over old sealant

Looking after it afterwards
Looking after new joints is easy:
- Avoid running a DIY bead over the old one
- Wipe joints with warm soapy water
- Get a leaking seal dealt with right away
- Use the extractor fan every time you shower
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
Upton Park questions
I let a flat near Woodgrange Park station. Can you help?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Do you cover Upton Park for new build mastic?

What colour sealant will you use?

Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
How much does new build mastic cost in Upton Park?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Is it normal for sealant to crack in a new home?
It’s common, and there are normally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
What the job involves on each surface
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
- Let us know if you’ve seen damp or leaks
