How we handle facade sealing in Summerstown
Some clients need every window on a block resealed; others need a few leaking frames sorted. 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. If you are dealing with cladding panel joints that have opened up and leaks at window and door perimeters, we can put it right, whatever the surface. A single leaking joint is often how a building in Summerstown first comes to us: we look at the rest while we’re there and tell you what we find.
Construction in a London area such as Summerstown means working on constrained sites: limited storage, booked deliveries and access shared with other trades. Mastic is normally one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Common questions from Summerstown clients
Can you work at a site such as Garratt Business Park, by Summerstown?
Yes. Estates, retail parks and business parks around Summerstown, Garratt Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
How much does the work cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.
Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.
Can you look at water coming in around a frame?
Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
Can the building stay open while you work?
Normally, yes. Phased work can be planned so areas stay in use.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Work on the window or framing system itself
- Damaged frames that need replacing
Not sure which it is? You can call 01277 525 020 or send details through our quote form and we will tell you honestly.
Joints and surfaces we work on
- Stone and brick facade joints
- Window and door perimeters
- Coping and flashing joints
- Perimeter joints where frames meet the structure
- Cladding panel joints
- Shopfront frames
Different surfaces, different methods
Precast concrete panels
Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use.
When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Looking after the joints
Regular inspection catches problems early. In particular:
- Avoid patch repairs on failed facade joints
- Report water ingress at frames as soon as it shows
- Keep pressure washers away from fresh sealant
- Clear debris that holds water against joints
Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed rather than sitting against the joints.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and cuts time on site.

Do you need facade sealing in Summerstown?
Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.
Site and facilities staff are often the first to spot these:
- Facade joints cracked through the middle
- Old perimeter mastic that has dried out
- Failed sealant on precast panel joints
- New sealant peeling off old mastic
Units on estates such as Garratt Business Park, less than half a mile to the south-west of Summerstown, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Planning a London job such as one in Summerstown starts with access. Give us the hours we can be on site and we will schedule to suit.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- 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.
What we need from you
- Make sure the joints can be reached
- Send any specification or drawings in advance
- Tell us your opening times and when work is allowed

Advice
Building and refurbishing in Summerstown
A good number of hotels sit less than 2 miles from Summerstown. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. As part of Greater London, Summerstown is inside the ULEZ, which applies to every van on site. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
