Construction mastic for commercial buildings in Old Netley
On refurbishments, the mastic package usually includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. If you’re dealing with early adhesion failures on new external joints and a long mastic snag list close to completion, we can help, on internal decorators’ caulk, brick and block movement joints and floor and skirting junctions alike. Most enquiries from Old Netley start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
For a site near Old Netley, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Different surfaces, different methods
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer and we install what’s specified.
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly and baths are loaded where appropriate before sealing.
Work for main contractors and building owners
CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
What happens if it’s left?
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Leave it late and they turn up on the snag list. Halls, stores and units around places like Old Netley may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
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.
Why appoint us
- Matching to RAL references, product permitting
- Products installed to the manufacturer’s instructions
- Coloured sealants to suit the setting, where available
- Over 20 years of commercial sealing

What else we do in Old Netley
Building and refurbishing in Old Netley
The sea is no more than about 2 miles from Old Netley. 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. Old Netley is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.
On a healthcare site such as Fareham Community Hospital, 2.6 miles to the south-east of Old Netley, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. When a school such as Bursledon Church of England Infant School is extended or refurbished, the mastic package is often squeezed into the holidays.

Questions about Old Netley
Can being near the sea in Old Netley affect the sealant we need?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Is Old Netley too small for you to travel to?
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.
How do you work with the site programme?
We follow the trades through the building. Areas are sealed as they’re released by the site team, and we will raise anything that holds the work up.
How much does the work cost?
Each job is quoted on its own details. To get one, ring 01277 525 020 or send details through our quote form with a description of the work.
What accreditations do you hold?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. Tell us what site paperwork you need and we will confirm with the quote.
Does weather affect external mastic work?
External sealant needs a dry joint and a temperature within the product’s range. Damp, frost or condensation on frames can stop work so we usually switch to internal work when that happens.
Do you do fire-rated sealing on new builds?
We install fire-rated sealant where it is the specified product to the tested detail. We will flag if the detail needs a different product.
What sets the cost
A fixed quote reflects the actual work. It takes account of:
- The site’s rules and procedures
- Specialist products, such as fire-rated or hygienic sealants
- Working within restricted access windows
- Removal of failed or old sealant
Pricing mastic packages depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.
What to include in your enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Whether the building will be occupied during the work
- Any specification or named product
- Where the site is, with the postcode
- Clear photographs of the problem areas
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
