Photos, a specification or a quick description of the joints is enough to start a fixed quote.
General trades versus a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Commercial sealant contractors in Gilston
Sealant joints are easy to overlook until one lets water in. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors with sites in Gilston. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. The enquiries we see most involve wall and floor joints that have lost their seal and weathered facade sealant that no longer flexes, across external facade joints, movement joints in walls and floors and window and door perimeters.

Working on commercial sites near Gilston
Gilston sits in one of the drier corners of the country, the South East. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. There are a number of hotels within about 2 miles of Gilston. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme, with rooms done in turn while the rest stay let.
Trade counters and showrooms on estates such as Mead Park Industrial Estate (to the east of Gilston) need neat joints where customers see them. For premises near Harlow Town station, 0.6 miles south of Gilston, footfall is part of the plan: work is phased so shops and offices keep trading. If you have premises on more than one site, say at Mead Park Industrial Estate and Harlow Retail Park, one contractor and one quote can cover both.
Gilston is about 2 miles north-west of Harlow, in Hertfordshire. Across the CM20 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee.

Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Gilston, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- We begin with whatever information you have, whether that’s photos, a drawing or a list of locations.
- We work out why the joints have failed and fix a quote for the agreed scope.
- Before anything is cut out, we agree access, timings and sequence.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- We walk the completed areas with you and sign them off under the 12-month guarantee.
Before we start on site
- Tell staff and tenants when we’ll be in
- Tell us your opening times and when work is allowed
- Confirm the product named in the specification

Surface by surface
Window and door perimeters
Inside, cracked sealant around frames and window boards is common. We use a paintable product where decorating follows and a silicone where it doesn’t, in a shade that suits the frame.
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, and we’ll confirm the colours available for the specified product.
Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Roof leaks that only look like a joint problem
- Walls or slabs moving more than any sealant can take
If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think.
Surfaces we seal
- Movement joints in walls and floors
- External facade joints
- Washrooms and tea points
- Kitchen worktops and splashbacks
- Window and door perimeters
- Floor and threshold joints
Questions we’re asked in Gilston
Does a hotel in Gilston need to shut while its sealant is renewed?
Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.
Is a smaller place like Gilston outside your area?
Not at all. Gilston is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
What about asbestos in old mastic?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Can one contractor look after sealant on all our buildings?
Yes, across South East England, Greater London and all of Scotland. Each site gets the same process and a single contact.
What affects the price in Gilston
Your fixed quote is built from the real scope. It takes account of:
- The size and state of each joint
- Induction, permit and paperwork requirements
- Any access equipment needed
- Whether the work must be split into stages
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
What we need to price the job
We can often quote from photographs and a few details. Please tell us:
- Approximate linear metres or a joint schedule
- Anything awkward about access or site hours
- The postcode of the building
- The type of building and who uses it
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Log reseals in the O&M or maintenance records
- Have extract fans checked so wet areas dry out
- Check the asbestos register before anyone disturbs old sealant in an older building
- Check sealant as part of routine building inspections
Later works are the usual way new joints get damaged. Shop refits, new services and replaced fittings often break the seal around them. Where work has disturbed a joint, just call 01277 525 020 or send photos by email for a quote.
A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.
