New build mastic for homes and businesses in Manor House
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We’re often asked to deal with skirting joints opening in the first winter and second-fix sealing on new plots, across show homes, bathrooms & en suites and skirting & floors.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

FAQs for Manor House
Is parking an issue for new build mastic in Manor House?
Parking in Manor House, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Can you help a landlord with a rental near Harringay Green Lanes station?
Yes, rental work is part of what we do. You can ring 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.
How do I get a quote for new build mastic in Manor House?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or send us an email and tell us what needs doing and where.
Are you insured?
Yes. We are fully insured for every job we do.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Why has my new-build shower seal failed already?
There are normally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
What colour sealant will you use?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.

What else we do in Manor House
Can I do it myself?
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 fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
How it works
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. For a job in Manor House, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- 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.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in
- Let us know about parking restrictions

What we’re called out for in Manor House
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak.
If you can see any of these, it’s time to have the joints looked at:
- Skirting joints opening in the first winter
- Untidy sealant flagged on a snagging list
- Gaps opening as the house dries out and settles
- Sealant that never bonded to the surface
For new homes near Harringay Green Lanes station, it’s worth checking the sealant early, while snags are still fresh.

Different surfaces, different methods
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and primer used where needed.
