Why it’s worth doing now in Lashenden
Patching the worst lengths can be the right call on a tight budget. Where the remaining sealant is just as old, it tends to fail soon after, so access and set-up end up being paid for twice. We can price both options so you can decide on the facts. One visit to deal with every failing joint makes more sense than several trips to a place like Lashenden. Send photos of each area and we’ll quote for the lot.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Commercial sealant contractors in Lashenden, done properly
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 looking after property in Lashenden. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. We work on kitchen worktops and splashbacks, window and door perimeters and floor and threshold joints, and what we are called in for most is gaps behind commercial kitchen worktops and sinks and frame mastic that has hardened and come away from the wall. A single leaking joint is often how a building in Lashenden first comes to us: we look at the rest while we’re there and tell you what we find.
A lot of what we do in Lashenden is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
A job in a smaller place like Lashenden is usually a single building. We’ll want a full list and photos first, so the right products come on the day and nothing waits for a second trip.
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 spell out the cover before we begin.

Our process
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For work around Lashenden, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- First, details come to us: photos, drawings or a schedule of the areas, or we arrange a site visit.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- Site hours, access windows and the order of areas are agreed before we start.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- Backing and primer go in where needed, then the chosen sealant 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 us which areas need to stay in use
- Arrange parking or a loading space
- Make sure the joints can be reached
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Questions about Lashenden
Can you supply sealant in our brand colour for a site in Lashenden?
Yes, we can usually get close to most finishes from the product’s colour range. Send colour references or photographs and we’ll confirm what’s available for the product.
Is Lashenden off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can areas stay open during the work?
It’s normal for us to work in occupied buildings. We agree the order of areas, protect what’s nearby and close off only the section we’re sealing, until its cure time has passed.
Does the weather affect the work?
It can, when the joints are outside. 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.
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. We can work to your instruction process and site rules.
Is the old sealant taken out first?
Full removal is part of every quote. Sealing over traps water and lifts once the joint moves, so it isn’t something we do.
How long does a job like this take?
That varies with the scale of the job, though a typical visit typically takes part of a day on a small job and longer where several buildings or phases are involved. For bigger or phased jobs, we’ll set out a timescale with the quote.
Surface by surface
Shop fronts and retail fit-outs
Most shops can’t close for a reseal. Tell us your trading hours and access windows and we’ll plan around them, working in sections where that helps.
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. Replacement is the fix: strip, clean, dry and reseal, room by room if that suits the building.
How the quote is worked out
To price the job, we consider:
- Quantities, in metres or numbers
- Whether the work must be split into stages
- Distance, for remote addresses
- The site’s rules and procedures
Pricing sealant joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.
Sending details for a quote
However big the job, the same details help:
- Rough lengths or quantities, or drawings if you have them
- Access details, including height
- When you need the work done
- Clear photos of the problem areas
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or send details through our quote form.

Looking after the joints
To get the most from the new sealant:
- Have extract fans checked so wet areas dry out
- Log reseals in the O&M or maintenance records
- Deal with small splits before they become leaks
- Ask fit-out and M&E contractors to report any sealant they disturb
Later works are the usual way new joints get damaged. When fittings are moved or cabling added, the sealant nearby is easily disturbed. Where work has disturbed a joint, just phone 01277 525 020 or email a schedule or drawings for a quote.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Cleanability is something environmental health officers pay attention to.
Should maintenance staff do it?
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. Getting these wrong usually costs more in the end than doing them right.
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.
