Facade sealing for Offham sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
On site: what to expect
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 anything is cut or cleaned, and the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building. For a building around Offham, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Before we start on site
- Flag any permit to work we’ll need
- Share the asbestos register for older buildings
- Confirm the product named in the specification

Facade sealing in Offham, done properly
Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on shopfront frames, window and door perimeters and coping and flashing joints, and the usual reasons a site gets in touch are cold air coming in at window perimeters and weathered facade joints that have lost their grip. Searching for sealant specialists in Offham? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
For a site near Offham, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or send details through our quote form and we will come back to it.

When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Sites and facades in and around Offham
The area within 2 miles of Offham holds a number of hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. Central London is about 42 miles from Offham. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.
Hotel extensions and refits, at places such as Pelham Arms Hotel, which lies south-east of Offham, normally run between busy periods, so the sealing is squeezed into short windows. Units on estates such as Riverside Industrial Estate, 1.3 miles south-east of Offham, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

How the job changes by surface
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed.
Quoting for work in Offham
A fixed quote reflects the actual work. It takes account of:
- How much there is to seal
- Travel to remote or island sites
- The product specified
- The site’s rules and procedures
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Sending details for a quote
To price the job accurately, we need a clear picture of the site. Useful things to include:
- When you need the work done
- The type of building and who uses it
- Whether an asbestos survey exists
- Clear photos of the problem areas
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to speak to us on 01277 525 020 or send photos by email.
Common problems we fix in Offham
Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and the joint opens with the first real movement.
Site and facilities staff are often the first to spot these:
- Draughts around frames and panels
- Hard, chalky sealant that no longer flexes
- Unsightly perimeter sealant on a visible elevation
- Failed sealant on precast panel joints
For contractors at a college like East Sussex College, 1.9 miles to the south-east of Offham, perimeters and internal sealant are timed for the holidays.

Offham: questions and answers
Do you take on work at healthcare sites like Lewes Victoria Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Does your area include sites such as Riverside Industrial Estate, near Offham?
Yes. Estates, retail parks and business parks around Offham, Riverside Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.
Is it fine to apply new sealant on top of old?
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.
Is old mastic on our building likely to contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first; if it’s suspected, work stops until it has been tested. We don’t remove asbestos-containing materials.
Is the work guaranteed?
Yes. Our workmanship is backed for 12 months.
Will rain stop the work?
Rain and frost can pause external sealing. We plan for weather and keep you updated throughout the job.
How many days will you need on site?
That varies with the scale of the job, but the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Keeping the joints sound
A few simple habits keep the new joints working:
- Avoid harsh cleaners on facade sealant
- Plan facade sealing alongside redecoration
- Check the asbestos register before old mastic is disturbed
- Insist on a full cut-out when joints are renewed
Following storms, look inside for damp or staining near frames. An early report typically means a small reseal rather than a bigger repair.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and limits disruption.
