Sites and facades in and around Segensworth
The sea is no more than about 3 miles from Segensworth. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. At about 66 miles from central London, Segensworth is within reach of the capital. 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.
Further education sites such as Fareham College (to the south-east of Segensworth) are extended and refurbished from time to time, with mastic often programmed into the summer break. Hotel extensions and refits, at places such as The Solent Hotel, 0.7 miles north of Segensworth, typically run between busy periods, so the sealing is squeezed into short windows.

Other services in Segensworth
Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Why it’s worth doing now in Segensworth
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects, especially externally. Where an alternative is genuinely suitable, we’ll say so. One visit to deal with every failing joint makes more sense than several trips to a place like Segensworth, rather than one at a time. Send photos of each area and we’ll quote for the lot.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Faulty frames rather than failed sealant
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Designing joint widths or choosing the specification (that sits with the designer)
If you are not sure, just ring 01277 525 020 or email us and we will give you a straight answer.
Surfaces we seal
- Internal decorators’ caulk
- Floor and skirting junctions

- Window and door perimeters
- Cladding and panel joints
- Sanitary and kitchen joints
Diagnose, treat, sign off
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. For work around Segensworth, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

Advice
Signs you need construction mastic in Segensworth
On construction sites, joints typically fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated.
Site and facilities staff are often the first to spot these:
- Perimeter gaps outside the sealant’s range
- Cracks opening in caulked internal joints
- Sealant knocked or painted over by other trades
- Different trades sealing to different standards
Units on estates such as Solent Business Park, 0.7 miles to the north of Segensworth, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
What your quote should include
- Which product they’ll use, and why it suits the joint
- Their pre-qualification and accreditations
- Proof of insurance
- How they’ll work around occupants
How the job changes by surface
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer; we work to the specification and the manufacturer’s installation guidance.
Internal decorators’ caulk
Caulk is easy to apply badly. A neat, consistent caulk line makes the decorators’ job quicker and reduces snags.
Segensworth: questions and answers
Is Segensworth off your patch?
No. Places such as Segensworth are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Does the sea air around Segensworth change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Can you send site paperwork?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
What do you charge?
We don’t publish prices, as every site differs. Send photos or drawings and we will price it at a fixed figure.
Does weather affect external mastic work?
Outside, the joint has to be dry and the temperature within the product’s limits. Frosty or damp mornings can hold up external sealing, so internal areas are often done on those days.
