Common questions from Gipsy Hill clients
Would you work within a site like British Home & Hospital for Incurables?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can work at a site such as King's College London fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Will you stick to the specified products?
Specification first, then the maker’s instructions. Preparation, backing and depth follow the product guidance.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
What happens if the weather stops external sealing?
Outside, the joint has to be dry and the temperature within the product’s limits. Frosty or damp mornings can hold up external sealing.
How many days will you need on site?
It depends on the scope, though a typical visit typically takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. For bigger or phased jobs, we’ll set out a timescale with the quote.
What hours do you work?
We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
How we handle construction mastic in Gipsy Hill
Mastic tends to be one of the final packages before handover, which puts it right on the critical path. Mastic Doctor takes on mastic packages for main contractors and developers with projects in Gipsy Hill, sealing plot by plot or floor by floor as areas are released. The enquiries we see most involve failed sealant in an existing building being refurbished and new external sealant already peeling away, on brick and block movement joints, cladding and panel joints and floor and skirting junctions. A specialist sealant contractor works differently from a general builder: in Gipsy Hill, that means joint design, primers and backing rod as standard.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Gipsy Hill must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Commercial clients in Gipsy Hill
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.
Why act early in Gipsy Hill
Patching snags as they appear can feel quicker than a proper close-out. But one planned snagging pass through each area usually clears more for less disruption. We can run snagging as its own phase before handover. In Gipsy Hill, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Use the product the specification names
- Record the products used in the O&M file
- Protect sealed areas from following trades
- Ask cleaners to use soft cloths around fresh sealant
Record which products went where in the handover file. That helps the building owner maintain the joints later. Tell us what records you need and we’ll confirm with the quote.
One unsealed frame can let water into finished internal areas. That normally means redoing finishes in a completed area and possibly a delayed handover. A check of every frame before decorators start is worth the time.
On site: what to expect
Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. In Gipsy Hill, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We price from the drawings, specification and programme you send.
- You receive a fixed quote listing scope, products and phasing.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Let building users know which areas are affected
- Agree which areas must stay open
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

How the quote is worked out
To price the job, we consider:
- Phasing around occupants
- Induction, permit and paperwork requirements
- The size and state of each joint
- The product specified
We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.
What we need to price the job
For an accurate fixed quote, we need to understand the site. Send us:
- Clear photos of the problem areas
- Anything awkward about access or site hours
- Asbestos survey details if the building is older
- Approximate linear metres or a joint schedule
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’ll fill any gaps with a visit.
Contractors’ notes for Gipsy Hill
As part of Greater London, Gipsy Hill is inside the ULEZ, which applies to every van on site. Delivery slots and scarce storage shape how and when the mastic goes in. Several hotels sit less than 2 miles from Gipsy Hill. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Further education sites such as Capel Manor College (0.7 miles south-east of Gipsy Hill) are extended and refurbished from time to time, with mastic often programmed into the summer break. Hotel extensions and refits, at places such as Astra Palace Hotel, 0.5 miles to the north-east of Gipsy Hill, normally run between busy periods, so the sealing is squeezed into short windows. On a campus such as King's College London, which lies north of Gipsy Hill, new teaching buildings and residences are normally built and refurbished around the academic year.
Gipsy Hill is about 3 miles south-east of Stockwell, in Greater London. Commercial clients in Gipsy Hill use us for work on mastic packages. Gipsy Hill is one of 764 places we cover in Greater London.

When to bring in a specialist
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
