Mastic sealing in Staples Corner, done properly
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable. We’ll confirm the colours available for the specified product. The enquiries we see most involve a mix of products and colours from past repairs and no planned programme for sealant, on communal entrances and stairwells, shopfronts below residential blocks and external wall and movement joints. Facilities teams, main contractors and managing agents in Staples Corner tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For block-wide work, a place to park and store materials saves time on every visit.
Every job we finish is backed by a 12-month workmanship guarantee, in Staples Corner as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What happens if it’s left?
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows, and the complaints come with it. In Staples Corner, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

When something else is needed
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Masonry that has broken away beside the joint
- Glazing that needs replacing
If in doubt, call the office on 01277 525 020 or use the quote form and we will say what we think.
Where we work in Staples Corner
- Communal kitchens and washrooms
- Balcony and threshold joints
- Shopfronts below residential blocks
- Communal entrances and stairwells
- External wall and movement joints
- Window and door perimeters on blocks
Keeping the joints sound
After handover, these steps help:
- List the paperwork your organisation requires when you send details
- Keep bins and bikes away from communal door frames
- Group repairs into a planned programme
- Share the asbestos register when you send details
If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, routine checks spot the next round of repairs.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
Looking after buildings in and around Staples Corner
The 2 miles around Staples Corner include three care or nursing homes. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents. London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We fit the programme to your notice periods.
Buildings close to stations like Brent Cross West station (to the south of Staples Corner) are often flats over shops, with frame mastic to keep sound. Schools and community buildings such as Parkfield Primary School need frame and external mastic kept sound like any building. Churches, halls and community buildings such as Church of St John are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Cost factors for mastic joints
Before we quote, we look at:
- Joint width, depth and condition
- Phasing around occupants
- How much there is to seal
- Distance, for remote addresses
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- Specification clauses that apply
- Where the site is, with the postcode
- A wide shot and a close-up of the area
- Whether the building will be occupied during the work
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or use the quote form.
Your questions answered
Can you work in a care home near Staples Corner with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
How do we ask for a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email us. Include photographs or drawings if you have them.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Is Staples Corner in your area?
Yes. We cover Staples Corner, and the simplest way to start is to ring 01277 525 020 or send photos by email.
Do you do block-wide mastic programmes?
Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
How long does a typical visit take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Should maintenance staff do it?
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Diagnose, treat, sign off
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking one or more days per building, depending on the joint lengths and the access. In Staples Corner, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Let us know about inductions and permits
- Point out any areas we must not close
