Doing it in-house
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
How we handle facade sealing in Maze Hill
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on cladding panel joints, coping and flashing joints and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are failed seals around shopfront and entrance frames and failed sealant on precast panel joints. Most enquiries from Maze Hill start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Every London site, Maze Hill included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Keeping the joints sound
A few simple habits keep the new joints working:
- Investigate damp beside windows promptly
- Keep sills, gutters and drainage paths clear
- Keep pressure washers away from fresh sealant
- Plan facade sealing alongside redecoration
After heavy weather, check vulnerable elevations for signs of water inside. An early report typically means a small reseal rather than a bigger repair.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it.
Mastic packages on Maze Hill sites
The ULEZ covers the whole of Greater London, Maze Hill included, so site vehicles need to meet its standards or pay the daily charge. Deliveries are booked and storage is tight, so mastic materials come in as needed. Maze Hill has plenty of hotels close by, all within 2 miles. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
For contractors refurbishing units at places like Angerstein Business Park, which lies north-east of Maze Hill, the mastic covers cladding panels, roller-door and window perimeters. Hotel extensions and refits, at places such as King William Hotel, under half a mile north of Maze Hill, typically run between busy periods, so the sealing is squeezed into short windows. Further education sites such as Bellerbys College London (to the west of Maze Hill) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Different surfaces, different methods
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.
Perimeter joints at frames and structure
Perimeter joints at frames often show their age first. They are cut out, cleaned, backed and resealed using a sealant classified for that use.
How a job runs
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Planning a London job such as one in Maze Hill starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Preparing the site
- Share your working hours and any access restrictions
- Tell us which areas need to stay in use
- Let us know about inductions and permits

Related advice
What happens if it’s left?
Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Questions about Maze Hill
Can you work at a site such as Angerstein Business Park, by Maze Hill?
Yes, sites like Angerstein Business Park are within our area, along with the rest of Maze Hill. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Can you work on a hospital site such as Blackheath Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Do you seal facades in winter?
Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Can you look at water coming in around a frame?
Yes. We check the sealant joints and report what we find. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
