Advice
Mastic sealing for commercial buildings in St Ives
Across St Ives and the rest of Hampshire, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. If you have repeated reactive repairs to the same buildings and damp patches beside frames, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in St Ives is the same: the right product in a properly prepared joint.
In and around smaller places like St Ives, 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.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Asbestos-containing sealant, which we don’t remove
- Failed window or door frames, which need a window contractor
- Misted or failed double-glazed units
If you are not sure, just ring 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Shopfronts below residential blocks
- Communal kitchens and washrooms
- Balcony and threshold joints
- External wall and movement joints
- Window and door perimeters on blocks
- Communal entrances and stairwells
Cost factors for mastic joints
These are the things that shape the price:
- The size and state of each joint
- Phasing around occupants
- The total length or number of joints
- Which sealant the job calls for
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- Clear photographs of the problem areas
- The type of building and who uses it
- Access details, including height
- When you need the work done
The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call 01277 525 020 or email us if you’d rather talk the job through.

Why deal with it now?
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows, and the complaints come with it. One visit to deal with every failing joint makes more sense than several trips to a place like St Ives, rather than one at a time. Send photos of each area and we’ll quote for the lot.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Why appoint us
- CHAS accredited contractor

What the job involves on each surface
Estate-wide resealing programmes
Priority order can follow condition, complaints or your maintenance plan. Quotes can be per block or for the full programme.
Commercial and mixed-use buildings
Where retail and residential share a building, so phasing has to suit both. We plan around the site hours and access windows you give us.
FAQs: St Ives
Is St Ives off your patch?
Not at all. St Ives is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Does your area include sites such as Ashley Heath Industrial Estate, near St Ives?
Yes, sites like Ashley Heath Industrial Estate are within our area, along with the rest of St Ives. Photos and a short description are enough for a first look.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How much does the work cost?
We don’t publish prices, because every site is different. Send photos or drawings and we will price it at a fixed figure.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit usually takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we will set out a timescale with the quote.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Keep a record of when each building was resealed
- Start inspections with the most exposed faces
- Include mastic in your cyclical inspections
- Group repairs into a planned programme
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
For owners and agents in St Ives
Three care or nursing homes sit less than 2 miles from St Ives. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
Historic properties like Avon Tyrrell House (4.5 miles south-east of St Ives) show the age of some local stock, where frame mastic must suit soft brick or stone. Site managers at schools like St Ives Primary & Nursery School can fit frame mastic into the summer works. If you’re responsible for a building such as All Saints, frame and door mastic needs the same attention as any other property.
