Mastic sealing for businesses in Steephill
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Aftercare for building managers
To get the most from the new sealant:
- Track which buildings were done and when
- Keep bins and bikes away from communal door frames
- Encourage occupiers to report problems at frames
- Check sealant joints during planned building inspections
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
One failed perimeter usually means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.
Mastic sealing for commercial buildings in Steephill
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. If you have old repairs sealed over failed mastic and mastic failing across several blocks on an estate, we can help, on external wall and movement joints, shopfronts below residential blocks and window and door perimeters on blocks alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Steephill, preparation and product choice get the time they need.
Around smaller places like Steephill, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common problems we fix in Steephill
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. It can’t stretch properly and it tears.
Clients usually get in touch after noticing something like this:
- Draught complaints from residents or tenants
- Leaks at window and door perimeters
- Complaints coming in block by block
- Failed external movement joints
For agents with blocks near Shanklin station, 3.5 miles north-east of Steephill, a block-wide mastic programme deals with frames, balconies and entrances in one go.
What your quote should include
- Will failed sealant be removed rather than covered?
- Whether primer will be used where the manufacturer specifies it
- Their plan for phasing and protecting the area
- The terms of the workmanship guarantee

How the quote is worked out
A fixed quote reflects the actual work. It takes account of:
- The site’s rules and procedures
- Backing rod, priming and other preparation
- Access and working height
- Removal of failed or old sealant
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
Before you send an enquiry
We can often quote from photographs and a few details. Please tell us:
- Any dates the work must fit around
- The postcode of the building
- Drawings or a marked-up plan, if available
- Whether an asbestos survey exists
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or email drawings and photos if you’d rather talk the job through.
Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Leaks through the frame itself rather than the perimeter
- Misted or failed double-glazed units
- Materials that need asbestos testing before work
If you’re not sure, just call the office on 01277 525 020 or use the quote form and we’ll give you a straight answer.

Looking after buildings in and around Steephill
Steephill lies within about 1 mile of the sea. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. Rainfall across the South East, Steephill included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building typically need attention first.
If your remit includes a building such as St Francis Catholic and Church of England Primary Academy, frame and door mastic can be programmed for the holidays. Property owners at sites such as Ventnor Industrial Estate, 0.8 miles north-east of Steephill, can have mastic renewed between lettings.
Steephill is about 3 miles south-west of Shanklin, in the Isle of Wight. We cover Steephill and the rest of the Isle of Wight, with the same fixed quotes and 12-month guarantee as everywhere else.

On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a day or two for a single block, longer for an estate programme, and we clear our waste as we work. Jobs in and around smaller places like Steephill are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

Advice
Questions about Steephill
Is a smaller place like Steephill outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Do you work for managing agents with blocks near Shanklin station?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
Do you do block-wide mastic programmes?
Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Can you seal joints high up on a block?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.
What paperwork can you provide?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Why it’s worth doing now in Steephill
Looking at mastic during planned maintenance costs little. Leaving it until there’s a leak turns it into reactive work and less choice about when. One visit to deal with every failing joint makes more sense than several trips to a place like Steephill. Photos of every joint help us quote for the whole job.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
