Building and refurbishing in Queensbury
A 2-mile radius around Queensbury takes in plenty of hotels. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included. As part of Greater London, Queensbury is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
For contractors refurbishing units at places like Mill Yard Industrial Estate (1.1 miles north-east of Queensbury), the mastic covers cladding panels, roller-door and window perimeters. Projects at colleges like London College of Management Studies, 1.1 miles south-west of Queensbury, tend to run to term dates, so the mastic is planned tightly. University estates such as Westminster University, 1.7 miles south-west of Queensbury, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

How we handle construction mastic in Queensbury
Mastic Doctor has been a subcontractor on construction projects for over 20 years. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Queensbury, send drawings and the specification through our quote form. If you’re dealing with different trades sealing to different standards and existing joints on a refurb that need cutting out and resealing, we can help, whatever the surface. Looking for mastic applicators who cover Queensbury? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Construction in a London area such as Queensbury means working on constrained sites: limited storage, booked deliveries and access shared with other trades. Mastic is normally one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Your questions answered
Is a hospital such as Edgware Community Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Does your area include sites such as Mill Yard Industrial Estate, near Queensbury?
Yes, sites like Mill Yard Industrial Estate are within our area, along with the rest of Queensbury. Photos and a short description are enough for a first look.
Do you take on mastic snagging only?
Yes. Damaged, missed or untidy joints are stripped and done again properly to suit the programme.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
What will the job cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
Can you work while the building is occupied?
In the majority of cases, yes. We phase the work so most of the building stays in use.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Should maintenance staff do it?
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
What happens if it’s left?
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects and external joints are where it shows first. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. In Queensbury, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

How the quote is worked out
Before we quote, we look at:
- Joint width, depth and condition
- The total length or number of joints
- Specialist products, such as fire-rated or hygienic sealants
- The site’s rules and procedures
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
What to include in your enquiry
For an accurate fixed quote, we need to understand the site. Useful things to include:
- The product your specification calls for
- Drawings or a marked-up plan, if available
- How the joints are reached, and at what height
- When you need the work done
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
How a job runs
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a job in Queensbury, access comes first. Give us the hours we can be on site and we will schedule to suit.
- First we take quantities off the drawings and read through the specification.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Before we start on site
- Tell us your opening times and when work is allowed
- Point out any areas we must not close
- Let us know about inductions and permits
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Advice
When it isn’t the sealant
Some faults sit outside our scope, and we say so rather than covering them up:
- Designing joint widths or choosing the specification (that sits with the designer)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Glazing units that are cracked or misted
If you are not sure, just phone 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
