Mastic sealing in Alperton, done properly
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. We work on communal kitchens and washrooms, shopfronts below residential blocks and external wall and movement joints, and the failures we are asked to look at most are mastic failing across several blocks on an estate and damp patches beside frames. One point of contact handles commercial sealant work in Alperton from the first photos to the final walk-round, whether it’s one building or several.
For managing agents in Alperton, resident access, notice periods and the building’s rules shape the job. Work is planned with the agent so residents get notice and access is arranged in advance.
Our workmanship is guaranteed for 12 months, in Alperton as everywhere else we work. If our installation lets you down in that time, we return and fix it.

When it isn’t the sealant
Some faults sit outside our scope, and we say so rather than covering them up:
- Asbestos-containing sealant, which we don’t remove
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we will tell you honestly before you book.

We keep entrances and stairs open throughout. Work is planned in sections.
Alperton: questions and answers
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Does your area include sites such as Phoenix Trading Estate, near Alperton?
Yes. We cover Alperton and the area around it, including industrial estates, business parks and retail parks such as Phoenix Trading Estate. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
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.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Do you do block-wide mastic programmes?
We can. We survey and price each building, then work through them in order starting wherever is most urgent.
Work for main contractors and building owners
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a day or two for a single block, longer for an estate programme, and our waste is bagged and taken away as we go. In Alperton, 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.
- First we look at the mastic on each building and note what needs replacing.
- 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.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
What we need from you
- Send your site hours and access windows
- Confirm the product named in the specification
- Tell staff and tenants when we’ll be in

Advice
Block-wide mastic in Alperton
Blocks in London are usually run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We plan around the notices and access you arrange. Alperton has two care or nursing homes no more than 2 miles away. Care home owners need frame and external mastic kept sound without unsettling residents.
For owners of several units at places like Phoenix Trading Estate, under half a mile west of Alperton, one programme can deal with frame and external mastic across the lot. For a school such as Alperton Community School, perimeter mastic on windows and doors is a holiday job. If you look after a block within reach of Wembley Central station, 0.8 miles to the north of Alperton, frame and balcony mastic can be renewed on one programme.

What affects the price in Alperton
Before we quote, we look at:
- Travel to remote or island sites
- Specialist products, such as fire-rated or hygienic sealants
- How accessible the joints are
- The total length or number of joints
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Sending details for a quote
Diagnosis starts before we arrive. Let us know:
- When you need the work done
- Approximate linear metres or a joint schedule
- Access details, including height
- Photos of the joints, close up and from further back
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
General trades versus 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, which is what makes a joint last.
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.
