Commercial sealant contractors across AL9: what to expect
A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed. Primer is used wherever the manufacturer calls for it on that surface. We work on movement joints in walls and floors, washrooms and tea points and window and door perimeters, and the failures we’re asked to look at most are hardened, chalky sealant on south-facing or exposed elevations and layers of sealant, all of them failing.
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a few hours for one area, or a planned series of visits across a bigger building, and our waste is bagged and taken away as we go.
- Site photos, drawings or a visit tell us what’s there and how it has failed.
- 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.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- Completed areas are signed off with you under our 12-month guarantee.
How we quote

Shops, offices and hotels in AL9
In AL9, much commercial sealant work follows refits in shops, offices and hotels in places such as Hatfield, Hatfield Hyde and Welham Green. Where the joint is on show, a colour that suits the finish is part of the job.
The South East has large numbers of business parks and industrial estates, especially around the motorway corridors, and we cover AL9 along with the rest of the region.
Welham Green: Units at places like Oldings Corner Retail Park (to the north of Welham Green) are refitted as brands change, and the joints have to suit each new scheme. For tenants and agents on sites such as Alpha Business Park (under half a mile north-east of Welham Green), office fit-outs, reception joints and window perimeters are the usual sealant work.
Common problems we fix in AL9
Every sealant joint is a maintenance item. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. On a busy commercial site several of those pile up at once, which is why regular inspection pays.
It’s worth sending us details if you spot any of the following:
- Mouldy silicone around WCs, urinals and vanity tops
- Shrunken sealant along kitchen worktops and splashbacks
- Window and door perimeter joints that have cracked open
- Weathered facade sealant that no longer flexes
Owners, agents and contractors
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Whether you are 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.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Pass these on to them:
- Keep washroom and kitchen extraction working
- Look at the sealant around anything that has been moved or replaced
- Check sealant as part of routine building inspections
- Brief cleaning contractors to avoid scourers and blades on sealant
Brief your cleaning team on the joints that have been resealed. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces; a mild cleaner is all most joints need.
An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to, which makes sound joints worth keeping on top of.
Cost factors for sealant joints
To price the job, we consider:
- The site’s rules and procedures
- Joint width, depth and condition
- Whether the work must be split into stages
- Whether old sealant has to be cut out first
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.
What to include in your enquiry
However big the job, the same details help:
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
- Asbestos survey details if the building is older
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Doing it in-house
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
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.
Your questions answered
Is it OK to apply fresh sealant over existing beads?
Removal comes first, every time. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.
Do you cover AL9?
Yes. Sites across AL9 are covered, with one number for every area we cover.
Does commercial sealant work come with a guarantee?
Our workmanship on each job is backed by a 12-month guarantee. Public liability insurance is in place too.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
How do we get a quote?
Send photos, drawings or a list of locations. Where we need to see it, we’ll arrange a site visit, then send a fixed quote.
