How we handle new build mastic in Fulham
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. If you have skirting joints opening in the first winter and plot mastic for developers ahead of handover, we can help, whatever the surface.
London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement, in Fulham as anywhere.
We stand behind the work with a one-year guarantee.

What new build mastic looks like in Fulham
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Fulham is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For new homes near West Brompton station, it’s worth checking the sealant early, while snags are still fresh.
Fulham is about 2 miles south of Kensington, in Greater London. Fulham gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Across Greater London, we cover 764 places, Fulham among them.

Why act early in Fulham
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Fulham.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear quote before we start.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a few hours in a single home. In a London area like Fulham, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- 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
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

Fulham questions
Is parking a problem for a job in Fulham?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Can you help a landlord with a rental near West Brompton station?
Yes. We work for landlords and letting agents as well as homeowners. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We will go through the sealant items and agree what we will do.
Should I go to my builder first?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it is not sorted, or keeps failing, get in touch with us.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you do plot mastic on a new development?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we’ll give you a quote.
What affects the cost of new build mastic
The price is agreed before any work begins. It’s based on:
- When we can work, for business premises
- Access and height
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Asking for a quote
Before you ask for a quote, have a think about:
- The rough size of the job
- Any previous sealing or DIY work
- The address or postcode of the job
- A few pictures by email, if you can

What the job involves on each surface
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. We reseal them with a flexible sealant.
