Different surfaces, different methods
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Each joint is prepared, sealed and finished with a neat tooled line, and any bath is loaded with water first where that’s the agreed method.
External facade and movement joints
External movement joints often need primer, depending on the substrate. Primer goes on where the sealant maker calls for it.
Construction mastic in Borden, done properly
Mastic follows everyone else, which means it absorbs every delay upstream. We agree a sequence at the start and adjust it as the site manager releases areas, so applicators arrive when areas are genuinely ready. Sealing too early only means coming back once others have damaged it. Site teams most often ask us about different trades sealing to different standards and sanitary sealant damaged by following trades, across sanitary and kitchen joints, window and door perimeters and cladding and panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Borden is the same: the right product in a properly prepared joint.
Construction in and around smaller places such as Borden is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Cost factors for mastic packages
A fixed quote reflects the actual work. It takes account of:
- The site’s rules and procedures
- Phasing around occupants
- Whether old sealant has to be cut out first
- The product specified
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.
Sending details for a quote
To price the job accurately, we need to understand the site. Send us:
- Where the site is, with the postcode
- Specification clauses that apply
- How the joints are reached, and at what height
- Drawings or a marked-up plan, if available
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. If you have questions first, call the office on 01277 525 020 or send photos by email.
Contractors’ notes for Borden
Borden sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. Borden is about 46 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.
Historic houses such as Cowdray House (to the south-east of Borden) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
Borden is about 5 miles east of Petersfield, in West Sussex. We cover Borden and the rest of West Sussex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our West Sussex coverage takes in 373 places. Sites around Portsmouth have their own page, about 18 miles away.

Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
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 usually takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates, and our waste is bagged and taken away as we go. For a building around Borden, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.

Preparing the site

Related advice
What we are called out for in Borden
On a live site, contamination is the biggest threat to a new joint. Plaster dust, release agents, protective film residue and damp all stop sealant bonding so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Clients typically get in touch after noticing one or more of the following:
- Failed sealant in an existing building being refurbished
- A long mastic snag list close to completion
- Perimeter gaps outside the sealant’s range
- New external sealant already peeling away
New wings at hospitals like Midhurst Community Hospital, 4.1 miles south-east of Borden, bring long runs of window and panel joints to seal.
What to look for in a quote
- Whether their applicators hold CSCS cards
- How the joint faces will be prepared and primed
- Their approach to joint depth and backing
- How they handle RAMS and site documents
What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Damage to finishes by other trades after we’ve sealed
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Frames fitted out of tolerance
If in doubt, ring 01277 525 020 or email a schedule or drawings and we will say what we think before you book.
Surfaces we seal
- Floor and skirting junctions
- Cladding and panel joints
- Brick and block movement joints
- Window and door perimeters
- Sanitary and kitchen joints
- Internal decorators’ caulk
Borden: questions and answers
Is a smaller place like Borden outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work on a hospital site such as Midhurst Community Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Can you come in just for snagging?
Yes. Damaged, missed or untidy joints are stripped and done again properly to suit the programme.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
What joints do you seal on a new build?
External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging in one fixed quote.
