When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Frames fitted out of tolerance
- Specifying the product where the designer hasn’t
- Faulty frames rather than failed sealant
If you’re not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer before you book.

How we handle construction mastic in Steephill
Getting a subcontractor through site induction should be simple. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. Most enquiries involve a long mastic snag list close to completion and oversized or tapered gaps around new frames, on internal decorators’ caulk, floor and skirting junctions and window and door perimeters. A specialist sealant contractor works differently from a general builder: in Steephill, that means joint design, primers and backing rod as standard.
For a site near Steephill, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photographs and the programme and we will quote to suit.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Questions we’re asked in Steephill
Our building in Steephill is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Will you plan work around the academic year at somewhere like St Catherine's College?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Does weather affect external mastic work?
Weather matters for external sealing: the joint needs to be dry and within the product’s temperature range. We plan external elevations with that in mind.
Do you need construction mastic in Steephill?
A joint without backing rod or bond-breaker often fails early. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.
Common reasons buildings call us in:
- Snag items on joints that need redoing before handover
- Frame gaps too wide for sealant alone
- Window and door perimeters that won’t pass inspection
- Cracks opening in caulked internal joints
When a school such as St Francis Catholic and Church of England Primary Academy is extended or refurbished, the mastic package is often squeezed into the holidays.
What to look for in a quote
- Are they CHAS accredited or on Constructionline?
- The terms of the workmanship guarantee
- Who will actually carry out the work
- How the joint faces will be prepared and primed
How the job changes by surface
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. One applicator team gives the same finish everywhere.
Snagging before handover
Snags normally come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately.

What else we do in Steephill
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Steephill, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised straight away.
- Final snagging is completed and the 12-month guarantee applies.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Have the specification and drawings to hand
- Agree which areas must stay open
Getting a fixed quote
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or send photos by email if you’d rather talk the job through.

Mastic packages on Steephill sites
Steephill sits close to the coast, within about 1 mile. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.
For a contractor working at a hospital such as Arthur Webster Memorial Hospital for Children, 3.6 miles to the north-east of Steephill, perimeter and facade sealing is planned around patients and deliveries. Work at a hotel such as St Maur Hotel (less than half a mile north-east of Steephill) tends to be programmed around bookings, mastic included.
Steephill is about 3 miles south-west of Shanklin, in the Isle of Wight. We cover Steephill, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Steephill is one of 125 places in the Isle of Wight on our list. Sites around Portsmouth have their own page, about 16 miles away.
Commercial sites across PO38 are covered for mastic packages. Buildings on Love Lane, Steephill Road and Castle Court are within our area for mastic packages. You’ll find Steephill on or near the A3055. We also cover Ventnor (1 mile north-east), St Lawrence (1 mile west), Nettlecombe (2 miles north-west), Wroxall (2 miles north) and Bonchurch (2 miles east) for mastic packages. A short drive away, we cover Newport (8 miles north-west), Ryde (10 miles north), Cowes (12 miles north), Sandown (5 miles north-east), Shanklin (3 miles north-east) and East Cowes (12 miles north). Where a site is remote or on an island, travel and materials need planning ahead, so the full address helps from the start.
Landmarks near Steephill
We work on buildings around The Rose Inn and St Catherine's School. The nearest railway station is Shanklin station, roughly 3.5 miles north-east. Other landmarks nearby include Longshoremans Museum (0.6 miles east) and Arthur Webster Memorial Hospital for Children (3.6 miles north-east). The countryside around Steephill includes St Boniface Down.
Work for main contractors and building owners
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
Why act early in Steephill
On a refurbishment, there’s a choice between resealing existing frames and replacing them. Sound frames often need only a new perimeter seal and that’s a far smaller job. If the frame is life-expired, we will tell you. Around Steephill, it’s better to renew all the failing joints at once, rather than one at a time. 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. Tell us how the joints are reached and call for a quote.
