Commercial sealant contractors for Cheshunt sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Check the asbestos register before anyone disturbs old sealant in an older building
- Act on the first lifting edges rather than waiting
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Respect the cure time before reopening an area
We stand behind the workmanship with a 12-month guarantee. File the handover note with the building records.
Tenants and staff spot black or split sealant quickly. Replacing it on a planned cycle keeps complaints down.
Sealant specialists in Cheshunt
Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the paperwork side is in order: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. We work on floor and threshold joints, window and door perimeters and external facade joints, and the failures we are asked to look at most are expansion joints with the sealant torn out and earlier reseals applied straight onto the failed bead. Facilities teams, main contractors and managing agents in Cheshunt tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
If you look after more than one building near Cheshunt, the work can be planned as one programme, so standards and paperwork match across every site.
Many businesses in towns like Cheshunt work from older buildings that have been altered more than once. Where old meets new there are junctions between brick, render, timber and aluminium, and each needs the right sealant, in a colour that suits the frontage.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Our process
Before we leave any area, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Town-centre premises in Cheshunt may have limited parking, so tell us what’s nearby. On estates and business parks it’s typically simpler.
- Site photos, drawings or a visit tell us what’s there and how it has failed.
- A fixed quote follows, with removal and preparation included.
- Sequence, access and working times are settled before the first joint is touched.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- Completed areas are signed off with you under our 12-month guarantee.
What we need from you
- Let us know about inductions and permits
- Send any specification or drawings in advance
- Move anything stored against the joints

Advice
Questions we’re asked in Cheshunt
Do hotels near Cheshunt have to close for sealant work?
Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.
Do you offer colour-matched sealant for buildings in Cheshunt?
Yes, we can usually get close to most finishes from the product’s colour range. The quote lists the colours the product is made in.
Is failed sealant stripped out, or sealed over?
Removal comes first, every time. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
How do you keep disruption to occupiers down?
It’s mostly about sequence: we agree access windows, phase the work and keep enough facilities open. Let us know what can’t close and we’ll work around it.
Can you take on work for an FM or managing agent?
Yes. A large share of our work comes through facilities managers, managing agents and landlords, alongside main contractors. We can work to your instruction process and site rules.
Can you supply RAMS and insurance details?
The paperwork is agreed with the quote: most clients ask for RAMS, our insurance certificate and CSCS details. Every applicator holds a CSCS card.
When to call us in Cheshunt
When a bead peels cleanly off one face, it has failed in adhesion. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.
If one of these sounds familiar, it’s time for a closer look:
- Black mould through washroom sealant that won’t clean off
- Earlier reseals applied straight onto the failed bead
- Hardened, chalky sealant on south-facing or exposed elevations
- Smeared sealant across finishes from a rushed job
A business with units at Brookfield Retail Park and Theobalds Enterprise Centre needn’t use two contractors for its sealant.
Questions to ask before you book
- Will RAMS and insurance details be available?
- How the existing material will be dealt with
- How they’ll work around occupants
- What the guarantee covers, and for how long
For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Cheshunt. Several sites can go on one quote, so there’s one set of paperwork to deal with.
What the job involves on each surface
Commercial kitchens and tea points
In kitchens, sealant lines at worktops, sinks and wall panels take heat, grease and daily cleaning. They’re degreased thoroughly before resealing.
Facade and cladding joints
Facade sealant failures can be hard to spot from the ground. Close-up photographs or a site visit tell us what’s needed.

Cost factors for sealant joints
Before we quote, we look at:
- Removal of failed or old sealant
- Working within restricted access windows
- Distance, for remote addresses
- Induction, permit and paperwork requirements
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What to include in your enquiry
A good diagnosis starts with the right details. Let us know:
- Photos of the joints, close up and from further back
- Specification clauses that apply
- Whether the building will be occupied during the work
- The site address and postcode
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
