Mastic sealing for commercial buildings in Tinsley Green
Before work starts, most agents and landlords want the documents in order. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. If you are dealing with open joints in brickwork or panels and no planned programme for sealant, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Tinsley Green, that means joint design, primers and backing rod as standard.
In and around smaller places like Tinsley Green, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Substrate edges that need repairing first
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Frames that are rotten, warped or broken

What else we do in Tinsley Green
How the quote is worked out
To price the job, we consider:
- Phasing around occupants
- The size and state of each joint
- The site’s rules and procedures
- How much there is to seal
Pricing mastic joints depends on quantities, condition and access. Call for a quote.
What to include in your enquiry
However big the job, the same details help:
- The product your specification calls for
- The asbestos register, for older buildings
- Where the site is, with the postcode
- Approximate linear metres or a joint schedule
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or use the quote form.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes one or more days per building, depending on the joint lengths and the access, and our waste is bagged and taken away as we go. Rural sites near Tinsley Green may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.

Before we start on site

Advice
Why deal with it now?
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. One visit to deal with every failing joint makes more sense than several trips to a place like Tinsley Green, rather than one at a time. Photos of every joint help us quote for the whole job.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

After the work
To get the most from the new sealant:
- Share the asbestos register when you send details
- Keep bins and bikes away from communal door frames
- Make it easy for occupiers to report draughts
- Start inspections with the most exposed faces
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.
