Glazing silicone in Custom House, done properly
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We find the joint that is letting water in and renew it, and if it’s something sealant cannot fix, we will tell you. We work on glass-to-frame joints, glass balustrade bases and conservatory frames, and the jobs we see most are mouldy sealant around glass panels and water running down inside the glass.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Custom House as anywhere.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep harsh solvents off the silicone
- Open vents or windows to let moisture out
- Clean glass with a mild cleaner and a soft cloth
- Get a new leak looked at quickly
Avoid scraping near the new silicone when cleaning the glass. A soft cloth or sponge is best.
A leaking shower screen may not show at first. It can damage the floor or the ceiling below before you spot it.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
How the job changes by surface
Conservatory frames
Frame joints face sun and rain all year. A fresh bead seals them again.
Glass balustrade bases
Outdoor balustrade joints face the weather. A sound sealant joint keeps them tidy and dry.
Windows and doors in Custom House
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. With historic houses such as Queen's House (about 2.3 miles south-west) nearby, there’s older building stock in the area around Custom House as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
As a London address, Custom House can be tricky for parking: let us know about parking bays, permits or a driveway. In the older streets around St Matthew's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

If you need glazing silicone at a property on Tree Road, Ethel Road and Booth Road or a nearby road, our applicators can take on the job. Being close to the A1020, Custom House is simple for us to get to for glazing silicone. Other places close to Custom House include West Silvertown (1 mile south-west), Silvertown (1 mile south), Canning Town (1 mile north), Royal Docks (1 mile east) and Limmo Peninsula (1 mile west).

Why deal with it now?
Replacing windows or a shower screen isn’t needed for a failed joint. Sound glass and frames generally just need resealing, and we’ll tell you if that is not the case. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Custom House, the repair is bigger than the sealant job would have been.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
What you get with us
- Neat joints and a tidy finish
- Colour agreed with you before any work starts

How it works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from an hour or two to most of a day, depending on the size of the job from start to finish. In Custom House, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Getting ready for the visit
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises

When to call us in Custom House
Sealant laid over old sealant does not last. Many failed joints we see have been topped up rather than cut out leaving a path for water.
Keep an eye out for these signs:
- Glazing silicone that has cracked or come away
- Rooflight joints letting water in
- Leaks where conservatory glass meets the frame
- Water escaping where a screen meets the wall
For landlords with property near Custom House station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.
Before booking anyone
- Whether the sealant suits the joint
- Whether they seal over old material or remove it
- Is VAT in the price?
- Are they insured?
What affects the quote in Custom House
Your quote is based on your job. We look at:
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- The product the joint needs
- When we can work, for business premises
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Any access issues, like height or stairs
- Where the job is, and your postcode
- The rough size of the job
- Any previous sealing or DIY work
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.
