How we handle construction mastic in Marks Gate
Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. One contractor for all of it keeps the responsibility in one place. We work on internal decorators’ caulk, floor and skirting junctions and sanitary and kitchen joints, and the failures we’re asked to look at most are missed perimeter joints on a new elevation and snag items on joints that need redoing before handover. Looking for mastic applicators who cover Marks Gate? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Around Marks Gate, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How the quote is worked out
We price every job individually. The things that drive the figure:
- How accessible the joints are
- Quantities, in metres or numbers
- The product specified
- The size and state of each joint
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
Sending details for a quote
To price the job accurately, we need to understand the site. Send us:
- What the building is and how it’s used
- Clear photographs of the problem areas
- The site address and postcode
- When you need the work done
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or send photos by email.

New build and refits around Marks Gate
As part of Greater London, Marks Gate is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed. There are a number of hotels within about 2 miles of Marks Gate. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
New wings at hospitals like King George Hospital (to the south-west of Marks Gate) bring long runs of window and panel joints to seal. For contractors at a college like New City College, 1.4 miles south-west of Marks Gate, perimeters and internal sealant are timed for the holidays. School extensions, at buildings such as Crownfield Infant School, typically run to the summer holidays, mastic included.

Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates, and we clear our waste as we work. All of Greater London is in the ULEZ, and kerbside space in Marks Gate can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised straight away.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Send any specification or drawings in advance
- Tell staff and tenants when we’ll be in
- Explain the parking and delivery arrangements
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

What we can’t put right
Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Joints damaged after sign-off by following trades
- Approving fire stopping as compliant
Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we’ll tell you honestly.
Joints and surfaces we work on
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Floor and skirting junctions
- Cladding and panel joints
- Brick and block movement joints
- Window and door perimeters
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Flag uneven or tapered frame gaps early
- Brief following trades on areas that have been sealed
- Plan external elevations with the weather in mind
- Keep scrapers and abrasive pads off new beads
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known. Tell us what records you need and we will confirm with the quote.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out.
Surface by surface
Window and door perimeters
Gaps around frames have to be within the sealant’s range. Gaps outside the product’s range are raised with the site team before sealing starts.
Snagging before handover
Snags usually come from damage by following trades, missed joints or poor earlier work. We price snagging as part of the package or as a separate visit.
