About our mastic sealing in Forton
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. We work on balcony and threshold joints, external wall and movement joints and window and door perimeters on blocks, and the failures we are asked to look at most are repeated reactive repairs to the same buildings and window mastic that has split and shrunk. One point of contact handles commercial sealant work in Forton from the first photos to the final walk-round, whether it’s one building or several.
For landlords and associations with stock in and around Forton, grouping buildings into one visit saves travel. One quote can cover a whole list of addresses.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What we are called out for in Forton
Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.
These are often picked up first by site or facilities staff:
- Communal area joints that look neglected
- A mix of products and colours from past repairs
- Cracked, hardened mastic round windows on a block
- Mastic failing across several blocks on an estate
If you look after a block within reach of Portsmouth Harbour station (1.5 miles east of Forton), frame and balcony mastic can be renewed on one programme.

From enquiry to sign-off
Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Work in places the size of Forton is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

Advice
Looking after buildings in and around Forton
Forton lies within about 1 mile of the sea. On buildings near the shore, the side facing the weather typically needs its mastic renewed first, so it’s worth inspecting those sides more often. Forton is about 66 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.
Churches, halls and community buildings such as St John the Evangelist are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Student accommodation around universities such as University of Portsmouth - North Zone, 1.9 miles to the east of Forton, is usually managed block by block, which suits a planned mastic programme.
Forton is about 1 mile south-east of Gosport, in Hampshire. Businesses, contractors and managing agents in Forton use us for work on mastic joints, as part of our coverage of Hampshire. Forton is one of 723 places we cover in Hampshire.

Different surfaces, different methods
Planned maintenance
Resealing can be scheduled alongside other planned works on a timetable you set.
Window and door perimeters on blocks
Perimeter joints on blocks are best done elevation by elevation or block by block. Access is agreed with you before the quote is fixed.
Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Track which buildings were done and when
- Avoid piecemeal callouts where you can
- Make mastic part of routine maintenance checks
- Look at the sunniest and most exposed elevations first
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
Questions we’re asked in Forton
Can being near the sea in Forton affect the sealant we need?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.
Can you work in a care home near Forton with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we will work to them.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Can you reseal a whole block or estate?
Yes. We survey and price each building, then work through them in order, and the programme can start with the worst.
Can you seal joints high up on a block?
Every block is different. We agree access with you at quote stage so there are no surprises.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Can you quote from photographs?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.
Leave it or put it right?
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
