FAQs for Bow Common
Can you help a landlord with a rental near Limehouse station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Is Bow Common in your area for new build mastic?
Yes, Bow Common is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
What colour sealant will you use?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
When is the best time to reseal in a new build?
It depends on whether water is getting through. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Where are you based?
We work from Crawley. Our applicators cover Bow Common.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Do you take out the old sealant first?

Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
New build mastic for homes and businesses in Bow Common
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We work on plot handovers, windows & doors and bathrooms & en suites, and common reasons people get in touch are frame joints opening as the plaster dries and shower seals failing in the first year or two.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

What we are called out for in Bow Common
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
Signs it’s time to call us include:
- Joints pulling apart as timber shrinks
- Sealant that never bonded to the surface
- Plot mastic for developers ahead of handover
- Smeared, uneven beads picked up at snagging
Bow Common is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Questions to ask before you book
- How the colour is chosen
- What the cure time is
- Who turns up on the day
- Are they insured?
Joints and finishes in Bow Common homes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
For new homes near Limehouse station, it’s worth checking the sealant early, while snags are still fresh.

The nearest railway station is Limehouse station, roughly 0.8 miles south-west of the centre. Nearby you will also find Tower of London (2.4 miles west) and St Clement's Hospital (0.6 miles north-west). Open spaces near Bow Common include Tower Hill and Hollow Pond.
Keeping the joints in good condition
Aftercare is simple:
- Keep water off fresh sealant until it has cured
- Do not seal over failed sealant yourself
- Check bath and shower seals every few months as the house settles
- Clean sealant with mild detergent, not abrasives
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry and can be resealed later.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
What happens on the day
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs 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 Bow Common. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
- Let us know about parking restrictions

What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Leaks from pipes, valves or wastes, which need a plumber
- A tray or bath that isn’t properly supported, until it’s fixed
- Cracking that points to a structural problem
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Windows & doors
- Bathrooms & en suites
- Kitchens
- Show homes
- Skirting & floors
- Plot handovers
What happens if it’s left?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
