About our washroom sealing in Chapmore End
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. Our workmanship is guaranteed for 12 months. Most enquiries involve gaps where vanity tops meet the wall and washrooms that look worn because of the sealant, on IPS panels and cubicles, urinals and WCs and kitchens and tea points. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Chapmore End, that means joint design, primers and backing rod as standard.
Rural businesses near smaller places such as Chapmore End, from cafés to event venues, rely on washrooms and kitchens that stay clean. We plan the work around bookings and opening times.
A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or email us and we’ll come back to it.

What affects the price in Chapmore End
Quotes vary with the job. Expect it to depend on:
- Removal of failed or old sealant
- The site’s rules and procedures
- How accessible the joints are
- Working within restricted access windows
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
Sending details for a quote
We can often quote from photographs and a few details. It helps to include:
- Asbestos survey details if the building is older
- Clear photographs of the problem areas
- Access details, including height
- Rough lengths or quantities, or drawings if you have them
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 email drawings and photos.
What else we do in Chapmore End
Chapmore End: questions and answers
Is Chapmore End too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work around term dates at a campus such as Hertford College: Ware Campus?
Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
Will all the toilets be closed at once?
Only the area we’re working in is closed. Each room reopens after the sealant’s cure time and we start the next.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Common problems we fix in Chapmore End
Washrooms are warm, damp and full of organic residue, and sealant joints trap all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.
It’s worth sending us details if you spot any of the following:
- Failed sealant behind washroom basins
- Failed joints along IPS and cubicle panels
- Failed sealant in a tea point or staff kitchen
- Resealing that didn’t last because the old bead stayed
At a hospital like Hertford County Hospital, which lies south of Chapmore End, patient and staff washrooms are best done in short phases agreed with the ward.
Comparing quotes
- What site paperwork they can supply
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Their public liability cover
- Which product they’ll use, and why it suits the joint
Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Keep a record of which washrooms need attention
- Clear standing water from shower floors where possible
- Keep extract fans working and vents clear
- Brief cleaning staff to treat joints gently
If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, regular checks keep small problems small.
Water getting behind IPS panels and vanity units can swell the boards. Once that happens, a reseal won’t fix them.
Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Failed tanking beneath a wet-room floor or behind tiles
- A room that stays damp because ventilation isn’t working
- Leaking pipes, traps, wastes or cisterns, which need a plumber
If in doubt, call 01277 525 020 or send details through our quote form and we will say what we think before you book.
Joints and surfaces we work on
- Kitchens and tea points
- Urinals and WCs

A fixed quote is given before anything starts.
- First, the phasing is agreed so facilities stay open.
- Anything behind the joints that needs another trade is flagged.
- Failed sealant and residue are stripped out.
- We reseal with the grade suited to each area.
