About our facade sealing in Custom House
Managing agents and owners in Custom House ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. We work on stone and brick facade joints, coping and flashing joints and perimeter joints where frames meet the structure, and the failures we are asked to look at most are failed seals around shopfront and entrance frames and perimeter sealant that has split or peeled away. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Custom House, preparation and product choice get the time they need.
Construction in a London area such as Custom House means working on constrained sites: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Custom House: questions and answers
Do you cover business parks and estates near Custom House, such as Greenshields Industrial Estate?
Yes. Estates, retail parks and business parks around Custom House, Greenshields Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Would you work within a site like Newham University Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we’ll price it properly.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Do you replace failed glazing units?
No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.
General trades versus a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Clear debris that holds water against joints
- Add perimeter sealant to planned maintenance checks
- Insist on a full cut-out when joints are renewed
- Combine resealing with other works that need access
After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos.
Why it’s worth doing now in Custom House
Topping up a failed joint normally buys very little time. A full cut-out and reseal costs more on the day but lasts much longer. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

How a job runs
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. All of Greater London is in the ULEZ, and kerbside space in Custom House can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Getting the site ready
- Tell us what induction or permit system the site runs
- Warn occupants and staff about the work
- Send asbestos survey details if the building is pre-2000

Advice
How the job changes by surface
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus neutral-cure product, chosen for the frame and wall, goes in finished to throw water off the joint.
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building, so preparation and product choice matter.
Mastic packages on Custom House sites
As part of Greater London, Custom House is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed. Custom House has plenty of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
For contractors at a college like Newham College London (1.6 miles north of Custom House), perimeters and internal sealant are timed for the holidays. New wings at hospitals like Newham University Hospital (to the north of Custom House) bring long runs of window and panel joints to seal. Work at a hotel such as Sunborn Hotel (to the west of Custom House) tends to be programmed around bookings, mastic included.
