Facade sealing for Childs Hill sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
From enquiry to sign-off
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
Preparing the site
- Tell us your opening times and when work is allowed
- Tell us what induction or permit system the site runs
- For older buildings, check the asbestos register before work
Getting a fixed quote

About our facade sealing in Childs Hill
We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause, but not always. If the evidence points away from the sealant, we say so before quoting. We work on window and door perimeters, coping and flashing joints and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are unsightly perimeter sealant on a visible elevation and weathered joints at frame-to-structure perimeters. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Childs Hill is the same: the right product in a properly prepared joint.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. Mastic is usually one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Quoting for work in Childs Hill
These are the things that shape the price:
- The total length or number of joints
- Backing rod, priming and other preparation
- Specialist products, such as fire-rated or hygienic sealants
- Distance, for remote addresses
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you are ready.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Rough lengths or quantities, or drawings if you have them
- The site address and postcode
- Any dates the work must fit around
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Replacing glass or failed glazing units
- Movement beyond what any sealant can handle
- Damaged frames that need replacing
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we will tell you honestly.
Joints and surfaces we work on
- Window and door perimeters
- Coping and flashing joints
- Shopfront frames

- Stone and brick facade joints
- Cladding panel joints
Leave it or put it right?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, often turning up far from the joint. Getting scaffold, permits or access booked in Childs Hill takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Insist on a full cut-out when joints are renewed
- Keep sills, gutters and drainage paths clear
- Check the asbestos register before old mastic is disturbed
- Brief window cleaners about newly sealed joints
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly.
Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail.

Common questions from Childs Hill clients
Can you work in a London building with booked loading and goods-lift slots?

Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Can you just add new sealant on top?
No. New sealant won’t hold on old sealant, so the old bead is cut away. That is what makes the new joint last.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Facade sealing in Childs Hill: the local picture
The area within 2 miles of Childs Hill holds a good number of hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Childs Hill. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
For a contractor at a hotel such as MB Hotel, under half a mile south-west of Childs Hill, the mastic often has to be finished before a reopening date. When units on a site such as Brent Cross Shopping Park (to the north-west of Childs Hill) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For contractors at a college like College of North West London, 2.2 miles west of Childs Hill, perimeters and internal sealant are timed for the holidays.
