What affects the price in Staples Corner
Your fixed quote is built from the real scope. It takes account of:
- Travel to remote or island sites
- Whether the work must be split into stages
- How much there is to seal
- The site’s rules and procedures
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- What the building is and how it’s used
- Anything awkward about access or site hours
- Rough lengths or quantities, or drawings if you have them
- Any dates the work must fit around
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Construction mastic in Staples Corner, done properly
Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list, and every return visit costs time. Our aim is joints that pass at the first inspection, area by area through the programme. We work on brick and block movement joints, cladding and panel joints and sanitary and kitchen joints, and the usual reasons a site gets in touch are external joints sealed in damp or cold conditions that are now failing and sanitary sealant damaged by following trades. Most enquiries from Staples Corner start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Construction in a London area such as Staples Corner means working on constrained sites: limited storage, booked deliveries and access shared with other trades. Mastic is usually one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Why it’s worth doing now in Staples Corner
A cheaper sealant can look like an easy saving on a large package. A failed joint in the defects period costs far more than the product difference, especially externally. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Why choose Mastic Doctor in Staples Corner
- A fixed quote before work starts
- RAL and finish matching where the product range allows
- A range of standard colours, depending on the product
- Health and safety: CHAS accredited

Construction mastic around Staples Corner: how the place shapes the job
Site traffic in Staples Corner falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed. The area within 2 miles of Staples Corner holds plenty of hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
New wings at hospitals like BMI Hendon Hospital, 1.5 miles north of Staples Corner, bring long runs of window and panel joints to seal. New units and refits on sites such as Brent Cross Shopping Park, less than half a mile to the east of Staples Corner, need their panel and perimeter joints sealed to the specification.

Advice
Common problems we fix in Staples Corner
Dust is the enemy of adhesion on a construction site. Plaster dust, release agents, protective film residue and damp all stop sealant bonding so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Typical triggers for a call:
- Frame perimeters left unsealed or poorly sealed
- Perimeter gaps outside the sealant’s range
- A mastic package split between trades with no clear owner
- Bath and shower joints scraped during the final clean
Building work at universities like Middlesex University, 1.8 miles to the north of Staples Corner, is often timed for the summer, mastic included.

Common questions from Staples Corner clients
Could you schedule work at a campus like Middlesex University for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is a hospital such as BMI Hendon Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Is the mastic package guaranteed?
Our workmanship carries a 12-month guarantee from sign-off. Damage by others after we have finished isn’t covered.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
How long does a typical visit take?
It depends on the scope, though a typical visit typically takes whatever the programme allows, since the work follows the trades as areas are released. Larger or phased jobs take longer, and we will give you a timescale with the quote.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
Doing it in-house
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Joints damaged after sign-off by following trades
- Glazing units that are cracked or misted
- Designing joint widths or choosing the specification (that sits with the designer)
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.
