What happens if it’s left?
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go. Snagging can be priced as a separate stage. Older rural buildings around St Ives move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
Why us?
- Fixed quotes based on photographs, drawings or a visit
- Sealing commercial buildings since 2005
- Health and safety: CHAS accredited

Construction mastic in St Ives
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility. If you’re dealing with frame gaps too wide for sealant alone and external joints sealed in damp or cold conditions that are now failing, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in St Ives, that means joint design, primers and backing rod as standard.
Conversions of older rural buildings near smaller places such as St Ives bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What sets the cost
The price varies from site to site. Expect it to depend on:
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
- How much there is to seal
- How accessible the joints are
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.
Details that help us quote
Good information means a firmer quote. Helpful details to send:
- Where the site is, with the postcode
- The type of building and who uses it
- How the joints are reached, and at what height
- Your programme or deadline
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or ring 01277 525 020 or use the quote form to discuss it first.
After the work
To get the most from the new sealant:
- Note which sealant went where at handover
- Stick to the specified sealant rather than a generic substitute
- Brief following trades on areas that have been sealed
- Flag uneven or tapered frame gaps early
Our 12-month guarantee covers the workmanship from sign-off. The guarantee covers how we sealed, not later damage by other trades.
One unsealed frame can let water into finished internal areas. That typically means redoing finishes in a completed area and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.
When to call us in St Ives
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond, so preparation matters as much here as on a reseal.
These are often picked up first by site or facilities staff:
- Missed perimeter joints on a new elevation
- Sanitary sealant damaged by following trades
- External joints sealed in damp or cold conditions that are now failing
- Cracks opening in caulked internal joints
For contractors at a college like Sheiling College (0.6 miles north-east of St Ives), perimeters and internal sealant are timed for the holidays.
What to look for in a quote
- Health and safety accreditation such as CHAS
- Proof of insurance
- Whether old or failed sealant will be cut out, not overlaid
- Do they follow the manufacturer’s priming guidance?
Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. For work around St Ives, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- Drawings, specification and programme come to us.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
Getting the site ready
- Agree which areas must stay open
- Warn occupants and staff about the work
- Point out parking and an unloading spot
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Construction mastic in St Ives: the local picture
St Ives has a number of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Rainfall across the South East, St Ives included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
When units on a site such as Ashley Heath Industrial Estate, 1.6 miles to the north-west of St Ives, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For a contractor at a hotel such as St Leonards Hotel, 0.8 miles to the south-west of St Ives, the mastic often has to be finished before a reopening date.
St Ives is in Hampshire. We send applicators to St Ives for mastic packages. Across Hampshire, 723 places are covered, St Ives among them. For work in that direction, see our Southampton page.

St Ives: questions and answers
Do you take on work at healthcare sites like St Leonards Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can work at a site such as Sheiling College fit around teaching?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
What hours do you work?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
What does a mastic package normally include?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. The scope follows your specification.
What happens if the weather stops external sealing?
Conditions have to suit the product before external work starts. Sealing in poor conditions risks adhesion failure, so we wait rather than redo work.
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
How do we ask for a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
