New Build Mastic in Lambeth
New build mastic across Lambeth and nearby, with every bit of old sealant taken out first.
- Sealant that never bonded to the surface
- Untidy sealant flagged on a snagging list
- Internal frame sealant that has split
Keeping the joints in good condition
So the new joints stay in good condition:
- Photograph failed sealant before it’s redone
- Wait for the cure time before using a resealed shower
- Get a leaking seal dealt with right away
- Put sealant faults on your snagging list early
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.
New build mastic in Lambeth
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. If you are dealing with worktop and upstand sealant coming away and new-build shower sealant that has already split, we can put it right, whatever the surface.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in Lambeth as anywhere.
We stand behind the work with a one-year guarantee.

Landlord and commercial work in Lambeth
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
New build mastic around Lambeth
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
As a London address, Lambeth can be tricky for parking: let us know about parking bays, permits or a driveway. For new homes near Vauxhall station, it’s worth checking the sealant early, while snags are still fresh.

Different surfaces, different methods
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens suited to the job.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the number of plots. In Lambeth, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- 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 down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts

- Leaking fittings rather than failed sealant
- Disputes or warranty claims with your builder

FAQs for Lambeth
Is parking an issue for new build mastic in Lambeth?
Parking in Lambeth, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Is Lambeth in your area for new build mastic?
Yes. Our work covers London and the South East, and Lambeth is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early. Poor preparation at handover adds to it.
Do you work for landlords and businesses?
Yes. As well as householders, we work for landlords, agents, businesses and hotels.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or email us.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
What affects the quote in Lambeth
We quote each job individually. This is what makes a difference:
- The number and length of the joints
- Access and height
- The type of sealant required
- Mould in or behind the old joints
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What to tell us for a quote
What to tell us when you ask for a quote:
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
- Any previous sealing or DIY work
- Where the job is, and your postcode
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll come back to you with a quote.
