Frames, entrances and external joints in Fratton
Fratton sits close to the coast, within about 2 miles. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first; plan inspections around that. Fratton lies roughly 64 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations.
Blocks of flats and mixed-use buildings often cluster around stations such as Fratton station, under half a mile to the south of Fratton, and their window and balcony mastic tends to age at the same rate across a building. If you own or manage units on a site such as The Bridge Shopping Centre, less than half a mile to the south-west of Fratton, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

About our mastic sealing in Fratton
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. If you have worn sealant at communal door frames and repeated reactive repairs to the same buildings, we can put it right. Whoever orders the work in Fratton, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Owners with buildings around smaller places like Fratton often group mastic work so one visit covers several properties. Send the addresses and photos and we will quote for all of them together.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common problems we fix in Fratton
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and it tears.
If one of these sounds familiar, it’s time for a closer look:
- Estate-wide sealant that is simply worn out
- Damp patches beside frames
- Movement joints with sealant missing
- Worn sealant at communal door frames
Trustees of buildings like St Mary's Church can bring frame and external mastic into a planned maintenance list.

Keeping the joints sound
After handover, a little attention goes a long way:
- List the paperwork your organisation requires when you send details
- Prioritise elevations facing the weather
- Log resealing dates block by block
- Make mastic part of routine maintenance checks
If paintable sealant was used, decoration can follow once it has cured. Silicone usually can’t be painted, so keep decorators off it.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
Questions we’re asked in Fratton
Does your area include sites such as The Bridge Shopping Centre, near Fratton?
Yes, sites like The Bridge Shopping Centre are within our area, along with the rest of Fratton. Send details of the unit and the work through our quote form for a quick quote.
Can being near the sea in Fratton affect the sealant we need?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Can you send RAMS and CSCS details before starting?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
How much does the work cost?
We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.
Is Fratton in your area?
Yes. Fratton falls within our area, and the simplest way to start is to call the office on 01277 525 020 or send details through our quote form.
How do you reach windows on upper floors?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
Will you come and look before quoting?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.
Commercial clients in Fratton
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Cost factors for mastic joints
What shapes the price:
- Location, for remote and island sites
- Phasing around occupants
- Induction, permit and paperwork requirements
- Specialist products, such as fire-rated or hygienic sealants
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you are ready.
What we need to price the job
A few photos plus some basic facts will normally do. It helps to include:
- Your programme or deadline
- How the joints are reached, and at what height
- The asbestos register, for older buildings
- The product your specification calls for
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or email a schedule or drawings.
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a job in Fratton, the main thing is a clear picture of the work, so send photographs of each area. You will then get a fixed price for the work.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
What we need from you
- Agree which areas must stay open
- Let building users know which areas are affected
- Clear stock, furniture or equipment away from the joints
Quotes
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Why deal with it now?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once and is simpler to manage and budget. For buildings in places like Fratton, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Why appoint us
- RAL and finish matching where the product range allows
- CSCS-carded applicators
- Old sealant cut out, never sealed over
- CHAS accredited
