Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
How we handle commercial sealant contractors in Broad Colney
Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and in an occupied building failure normally announces itself as a stained ceiling or an unhappy tenant. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. Most enquiries involve a top-up bead over failed sealant, now lifting and gaps behind commercial kitchen worktops and sinks, on washrooms and tea points, floor and threshold joints and movement joints in walls and floors. A single leaking joint is often how a building in Broad Colney first comes to us: we look at the rest while we’re there and tell you what we find.
Quotes for commercial sealant in Broad Colney can come from photographs and a joint schedule, or from a walk-round, with the scope listed so everyone knows what’s included.
Business units in the countryside around places like Broad Colney are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

What affects the price in Broad Colney
What shapes the price:
- Whether the work must be split into stages
- The total length or number of joints
- Joint width, depth and condition
- Removal of failed or old sealant
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

- Asbestos survey details if the building is older
- A wide shot and a close-up of the area
- What the building is and how it’s used
- Where the site is, with the postcode

Why it’s worth doing now in Broad Colney
Reactive resealing, a leak at a time, tends to cost more overall than a plan. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in. Older rural buildings around Broad Colney move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Rural sites near Broad Colney may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We start with the evidence: photographs, drawings or a look on site.
- You get a fixed quote covering removal, preparation and the new sealant.
- 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.
Preparing the site
- Agree which areas must stay open
- Explain the parking and delivery arrangements
- Have the specification and drawings to hand
Getting a fixed quote

Advice
What we are called out for in Broad Colney
If sealant tears through its centre, it has failed cohesively. Usually the movement was too much for the sealant chosen: a bead laid too thin, an over-stretched joint or the wrong movement class. Replacing it like for like rarely holds.
Clients usually get in touch after noticing one or more of the following:
- External beads that have gone brittle and cracked
- Leaks that seem to come through a sealant line
- Gaps behind commercial kitchen worktops and sinks
- Smeared sealant across finishes from a rushed job
Shop fits at places like Colney Fields Shopping Park, 0.6 miles east of Broad Colney, leave counters, frontages and floor edges where the sealant colour is part of the finish.
Before you book anyone
- How the joint faces will be prepared and primed
- Which product they’ll use, and why it suits the joint
- Whether old or failed sealant will be cut out, not overlaid
- Are they CHAS accredited or on Constructionline?
Surface by surface
Commercial kitchens and tea points
Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. Proper degreasing comes before any new sealant, with a food-safe or hygienic product wherever food contact can happen.
Facade and cladding joints
Panel joints on cladding and rendered facades open and close with the temperature. The product has to suit the movement, and the depth has to be controlled with backing. Access, such as scaffold already up, is agreed before the price is fixed.
