Facade sealing in Woodside Park
Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Most enquiries involve weathered facade joints that have lost their grip and perimeter joints where frames meet the structure, on stone and brick facade joints, perimeter joints where frames meet the structure and window and door perimeters. A specialist sealant contractor works differently from a general builder: on jobs in Woodside Park, preparation and product choice get the time they need.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Woodside Park must meet its standards or pay the daily charge. Alongside that, sites normally need booked deliveries and a plan for where materials go.
Our workmanship is guaranteed for 12 months, in Woodside Park as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Leave it or put it right?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts. 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.
Pricing facade joints depends on quantities, condition and access. Ask us for a fixed quote.

How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- The product specified
- Location, for remote and island sites
- Backing rod, priming and other preparation
- Quantities, in metres or numbers
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.
What to include in your enquiry
There’s no need for a formal survey. These details are enough to start:
- Any dates the work must fit around
- Photos of the joints, close up and from further back
- Where the site is, with the postcode
- Rough lengths or quantities, or drawings if you have them
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or email us.
Questions we are asked in Woodside Park
Do you cover business parks and estates near Woodside Park, such as Finchley Industrial Centre?
Yes. Our area takes in Woodside Park and its surroundings, with estates and business parks such as Finchley Industrial Centre included. Send details of the unit and the work through our quote form for a quick quote.
Can you work around term dates at a campus such as Middlesex University?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you replace windows or glass?
No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.
Is it okay to overlay old mastic?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
Can you work on upper floors?
Access is planned with you before we quote. Let us know what access is in place or planned, and we’ll price the work around it.
New build and refits around Woodside Park
A number of hotels sit less than 2 miles from Woodside Park. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Woodside Park. Deliveries are booked and storage is tight, so mastic materials come in as needed.
Units on estates such as Finchley Industrial Centre (to the north-east of Woodside Park) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. For a contractor working at a hospital such as Finchley Memorial Hospital, 0.9 miles to the south-east of Woodside Park, perimeter and facade sealing is planned around patients and deliveries. For contractors at a college like Oak Hill College, 2.3 miles to the north-east of Woodside Park, perimeters and internal sealant are timed for the holidays.

Looking after the joints
After handover, these steps help:
- Check the asbestos register before old mastic is disturbed
- Plan facade sealing alongside redecoration
- Don’t wait for a second leak before calling
- Record the product and colour used on each elevation
Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead.
Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading inside the building.
How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a day or two for a few elevations, and longer where access has to be moved around the building, and our waste is bagged and taken away as we go. For a job in Woodside Park, access comes first. Send the building rules and access times with your enquiry.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
What we need from you
- Move anything stored against the joints
- Tell us which areas need to stay in use
- Tell us what induction or permit system the site runs

When to bring in a specialist
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.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
