Construction mastic in Alperton
On a new build, the mastic package is one of the last trades through each area, which puts it right on the critical path. Mastic Doctor takes on mastic packages for main contractors and developers, sealing plot by plot or floor by floor as areas are released. We work on internal decorators’ caulk, sanitary and kitchen joints and brick and block movement joints, and what we’re called in for most is different trades sealing to different standards and failed sealant in an existing building being refurbished. For commercial sealant work in Alperton, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Commercial clients in Alperton
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 will confirm with the quote.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. In Alperton, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- Drawings, specification and programme come to us.
- Quantities are measured and a fixed price returned.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
Getting the site ready
- Explain the parking and delivery arrangements
- Tell us which areas need to stay in use
- Send asbestos survey details if the building is pre-2000

What affects the price in Alperton
Each job is priced on its own details. The things that drive the figure:
- The total length or number of joints
- The size and state of each joint
- Access and working height
- Induction, permit and paperwork requirements
Larger quantities, tricky access or phasing 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 to include in your enquiry
A few photographs plus some basic facts will normally do. It helps to include:
- Anything awkward about access or site hours
- The asbestos register, for older buildings
- A wide shot and a close-up of the area
- When you need the work done
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.
What the job involves on each surface
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. Joints are sealed smooth so they’re easy to clean.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. Fire stopping design belongs to the designer and building control; we work to the specification and the manufacturer’s installation guidance.
When it isn’t the sealant
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Deciding which fire-stopping product a penetration needs
- Designing joint widths or choosing the specification (that sits with the designer)
- Damage to finishes by other trades after we’ve sealed
If you are not sure, just ring 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.
What we seal
- Floor and skirting junctions
- Window and door perimeters
- Cladding and panel joints
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Brick and block movement joints
General trades versus a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Contractors’ notes for Alperton
The area within 2 miles of Alperton holds a good number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Site traffic in Alperton falls within London’s ULEZ, like everywhere else in Greater London. Delivery slots and scarce storage shape how and when the mastic goes in.
Work at a hotel such as Wembley Hotel (to the north of Alperton) tends to be programmed around bookings, mastic included. Projects at colleges like Alexander Cromwell College (to the west of Alperton) tend to run to term dates, so the mastic is planned tightly. Units on estates such as Phoenix Trading Estate (to the west of Alperton) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
