Glazing & conservatory sealant in Plaistow, Greater London
Our applicators work in Plaistow on glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Cracked silicone between glass panels
- Water getting into a conservatory at the joints
- Black or yellowed silicone on glass joints
How to look after the new joints
To keep the joints looking good and working properly:
- Act on drips or damp patches early
- Use a gentle glass cleaner and a soft cloth
- Keep harsh solvents off the silicone
- Check the silicone on glass every year or so
Avoid scraping near the new silicone when cleaning the glass. Stick to a soft cloth.
A small conservatory leak soon spreads. Water runs along frames and down walls so it’s best dealt with right away.
How we handle glazing silicone in Plaistow
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. If you are dealing with water running down inside the glass and glazing silicone that has cracked or come away, we can help, whatever the surface.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in Plaistow as anywhere.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Plaistow homes and the weather
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Historic houses like Queen's House (about 3.2 miles south) are a reminder that the area around Plaistow has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Kaizen Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Memorial Community Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near West Ham station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Questions from Plaistow
Is Plaistow in your area for glazing silicone?
Yes. We work across London and the South East, and Plaistow is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Can you help a landlord with a rental near West Ham station?
Yes. We work for landlords and agents as well as homeowners. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Can I choose the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Is it enough to run a bead over the old sealant?
Many leaks we see come from exactly that. We remove the old silicone, clean the joint and reseal.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. 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. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at the glazing and agree which joints need resealing.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- The joints are checked before we leave.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Clear the area around the work
- Mention any tricky access

How we quote for glazing silicone
The quote reflects the job in front of us. We look at:
- Which sealant suits the joint
- Any working-time requirements on site
- The amount of work
- Mould in or behind the old joints
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.
Asking for a quote
To make quoting easier, let us know:
- Roughly how big the job is
- Photos by email, if that is easy
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we’ll talk you through the work.

Different surfaces, different methods
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We reseal with a suitable glazing silicone.
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Landlords, agents and businesses in Plaistow
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
