Mastic sealing for commercial buildings in Bowes Park
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. If you are dealing with draughts at frames across a block and a mix of products and colours from past repairs, we can help. A specialist sealant contractor works differently from a general builder: on jobs in Bowes Park, preparation and product choice get the time they need.

From enquiry to sign-off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We inspect the joints, building by building, and record what has failed and why.
- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Confirm the product named in the specification
- Move anything stored against the joints
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Your questions answered
Will you take on work at estates like St. George's Industrial Estate, close to Bowes Park?
Yes, sites like St. George's Industrial Estate are within our area, along with the rest of Bowes Park. To start, just give us a call on 01277 525 020 or email us with the unit, the joints involved and your access times.
Do you work for managing agents with blocks near Alexandra Palace station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
What paperwork can you provide?
Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.
Honest limits
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Frames that are rotten, warped or broken
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
Not sure which it is? You can ring 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
Surfaces we seal
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Communal kitchens and washrooms
- External wall and movement joints
- Balcony and threshold joints
- Shopfronts below residential blocks
Why act early in Bowes Park
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work and less choice about when. Getting scaffold, permits or access booked in Bowes Park takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What you get with us
- One number for every site we cover
- Fully insured, including public liability cover
- A Constructionline member, so easy to vet
- Products installed to the manufacturer’s instructions

Should maintenance staff do it?
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, which is what makes a joint last.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Maintenance after handover
To get the most from the new sealant:
- Group repairs into a planned programme
- Share your contractor requirements early
- Check sealant joints during planned building inspections
- Protect low-level joints in entrances
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
