Contractors’ notes for Atherington
Atherington is within about 1 mile of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Atherington is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.
Projects at schools like St Mary's CofE Primary School work to term dates, so mastic is programmed tightly. Building work at universities like University of Chichester (Bognor Campus) (3.8 miles west of Atherington) is often timed for the summer, mastic included. When units on a site such as Rudford Industrial Estate, 0.8 miles to the north of Atherington, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Facade sealing in Atherington
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. The enquiries we see most involve previous reseals run over old sealant and water coming in around window frames, across shopfront frames, coping and flashing joints and window and door perimeters. Searching for sealant specialists in Atherington? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Construction in and around smaller places such as Atherington is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Diagnose, treat, sign off
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a building around Atherington, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Getting the site ready
- Tell us which areas need to stay in use
- Flag any permit to work we will need
- Share the asbestos register for older buildings

FAQs: Atherington
Can work at a site such as University of Chichester (Bognor Campus) fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is a smaller place like Atherington outside your area?
No. Places such as Atherington are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Do you replace windows or glass?
No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.
Can you work on upper floors?
We agree access with the client at the start. Let us know what access is in place or planned, and the quote will reflect it.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited and a Constructionline member.
What type of sealant goes on window perimeters?
The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them.
What sets the cost
We price every job individually. The things that drive the figure:
- The size and state of each joint
- How accessible the joints are
- Quantities, in metres or numbers
- Location, for remote and island sites
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.
Details that help us quote
A few photos plus some basic facts will normally do. It helps to include:
- The site address and postcode
- How the joints are reached, and at what height
- Rough lengths or quantities, or drawings if you have them
- Asbestos survey details if the building is older
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Installing or repairing glazing systems
- Joints whose design needs changing by the specifier
- Damaged frames that need replacing
If in doubt, call 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
What we seal
- Perimeter joints where frames meet the structure
- Cladding panel joints
- Coping and flashing joints
- Window and door perimeters
- Shopfront frames
- Stone and brick facade joints
For managing agents and facilities managers
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
What happens if it’s left?
Topping up a failed joint normally buys very little time. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. Halls, stores and units around places like Atherington may not be checked every day, so a failed joint can leak for a while before anyone sees it. 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. Tell us how the joints are reached and call for a quote.
