Mastic sealing for Bognor Regis sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
What sets the cost
Each job is priced on its own details. The things that drive the figure:
- Location, for remote and island sites
- Phasing around occupants
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
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.
What we need to price the job
However big the job, the same details help:
- Photos of the joints, close up and from further back
- When you need the work done
- The product your specification calls for
- Approximate linear metres or a joint schedule
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or email us.
How we handle mastic sealing in Bognor Regis
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. We work on external wall and movement joints, window and door perimeters on blocks and communal entrances and stairwells, and the usual reasons a site gets in touch are occupiers reporting cold air round windows and old repairs sealed over failed mastic. Looking for mastic applicators who cover Bognor Regis? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
A large place such as Bognor Regis usually has blocks of flats, housing association estates and commercial buildings with mixed ownership. A planned programme lets failed mastic be renewed block by block across an estate.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Block-wide mastic in Bognor Regis
The sea is no more than about 1 mile from Bognor Regis. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, and they deserve more regular inspection. Rainfall across the South East, Bognor Regis included, is lower than in many parts of the UK. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
For a school such as The Regis School, perimeter mastic on windows and doors is a holiday job. For agents with blocks near Bognor Regis station, 0.5 miles to the south-east of Bognor Regis, a block-wide mastic programme deals with frames, balconies and entrances in one go.
Bognor Regis is in West Sussex. Across the PO21 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Bognor Regis is one of 373 places in West Sussex on our list. Our Portsmouth page has more on work in that area, about 17 miles away.

Questions about Bognor Regis
Will you work in a care home in Bognor Regis without moving residents out?
Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we will work to them.
Does your area include sites such as Durban Road Industrial Estate, near Bognor Regis?
Yes. Estates, retail parks and business parks around Bognor Regis, Durban Road Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Different surfaces, different methods
Tenement and older buildings
Older mastic can contain asbestos and the register is checked before anything is disturbed. Suspect material is tested before work continues.
Communal areas
Entrance doors, screens and corridor junctions in communal areas all have sealant joints. Fresh joints make shared areas look looked after.
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
On site: what to expect
Before we leave any area, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. For premises in central Bognor Regis, deliveries and parking need a bit of planning, whereas edge-of-town units normally have yard space. Let us know what’s there when you send details.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Share your working hours and any access restrictions
- Share the asbestos register for older buildings
- Let building users know which areas are affected

Common problems we fix in Bognor Regis
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone, so these repairs rarely last.
These are often picked up first by site or facilities staff:
- Water getting in round frames after rain
- Cracked, hardened mastic round windows on a block
- Repeated reactive repairs to the same buildings
- Movement joints with sealant missing
Owners of student blocks near University of Chichester (Bognor Campus) (1 mile east of Bognor Regis) can schedule frame and external mastic for the summer vacation.
What your quote should include
- What site paperwork they can supply
- Which product they’ll use, and why it suits the joint
- Their plan for phasing and protecting the area
- Their public liability cover

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. Cutting out and resealing properly does it once. If one joint has failed on your building in Bognor Regis, others of the same age may be close behind. Renewing them in one programme saves time later.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
