Should maintenance staff do it?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Construction mastic for commercial buildings in Hill Grove
Buyers, tenants and clients notice sealant lines long before they notice the structure. A smeared bead round a window or a gap behind a worktop ends up on the snag list and clearing them late eats into the handover window. We seal so the snag list stays short, whatever the size of the scheme. We work on floor and skirting junctions, cladding and panel joints and brick and block movement joints, and the failures we’re asked to look at most are existing joints on a refurb that need cutting out and resealing and internal caulk splitting as the building dries out. Facilities teams, main contractors and managing agents in Hill Grove tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Sites around smaller places like Hill Grove can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photos and the programme and we will quote to suit.
A 12-month guarantee applies to all our work. If an installation problem shows up, give us a call on 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

What the job involves on each surface
Fire-rated sealant where specified
Not every penetration suits a sealant. Other products are used for some services and gaps. Tell us what records you need and we’ll confirm with the quote.
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. We check them during the first walk-round and flag any that need packing or adjusting.

Maintenance after handover
For the best life from the joints:
- Flag uneven or tapered frame gaps early
- Share drawings and the specification as soon as possible
- Brief the final clean team to avoid blades near sealant
- Stick to the specified sealant rather than a generic substitute
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known. We can confirm the handover information you need when we quote.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.
When to call us in Hill Grove
On construction sites, joints typically fail early because of when they were sealed, not what was used. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage.
Any of the following is a good reason to get the joints checked over:
- Internal caulk splitting as the building dries out
- Frame gaps too wide for sealant alone
- Existing joints on a refurb that need cutting out and resealing
- New external sealant already peeling away
When units on a site such as Waltham Business Park, 0.8 miles to the south-west of Hill Grove, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
What your quote should include
- How they handle RAMS and site documents
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Is the sealant right for the movement and the substrate?
- Will CSCS-carded applicators be on site?
