FAQs: Higham Hill
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
Will you work in a care home in Higham Hill without moving residents out?
Yes. We work around residents’ routines, a room or two at a time. Noise and disruption are kept to a minimum.
Do you guarantee washroom sealing?
There is a 12-month guarantee on our workmanship backed by public liability insurance.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What do you charge?
Every job gets its own fixed quote. To get one, speak to us on 01277 525 020 or email us with a description of the work.
About our washroom sealing in Higham Hill
Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. If you have shower tray joints that have opened up and sealant laid over old silicone and now peeling, we can help. A specialist sealant contractor works differently from a general builder: in Higham Hill, that means joint design, primers and backing rod as standard.
In Higham Hill, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Quoting for work in Higham Hill
Your fixed quote is built from the real scope. It takes account of:
- Location, for remote and island sites
- Any access equipment needed
- How much there is to seal
- Whether the work must be split into stages
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.
Sending details for a quote
Diagnosis starts before we arrive. Let us know:
- The asbestos register, for older buildings
- Where the site is, with the postcode
- Any specification or named product
- When you need the work done
Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to ring 01277 525 020 or use the quote form.
Leave it or put it right?
Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
A quote for washrooms and wet areas depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Doing it in-house
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
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 we are called out for in Higham Hill
Commercial cleaning is harder on sealant than everyday use. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges, and dirt and mould then get a foothold.
Typical triggers for a call:
- Open joints along basins and vanity units
- Users noticing mouldy joints
- Failed joints along IPS and cubicle panels
- Shower tray joints that have opened up
Customer toilets in retail centres such as Ravenside Retail Park, 0.9 miles north of Higham Hill, rarely close, so resealing is phased.

Keeping Higham Hill washrooms open while we work
Busy London buildings need some toilets open at all times, so we phase the work core by core or floor by floor with the building manager. Higham Hill has 14 care or nursing homes no more than 2 miles away. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Work is agreed with the manager, around residents’ routines.
Student showers at universities like University of Portsmouth Walthamstow Campus (to the south-east of Higham Hill) see more use than most, and their silicone shows it. Office toilets at parks like Uplands Business Park (to the south-west of Higham Hill) take steady weekday use, and mouldy silicone soon shows.
Higham Hill is about 1 mile north-west of Walthamstow, in Greater London. Across the E17 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.
