How we handle mastic sealing in Alfriston
Before work starts, most agents and landlords want the documents in order. 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, with public liability insurance. If you have water getting in round frames after rain and estate-wide sealant that is simply worn out, we can help, on communal entrances and stairwells, external wall and movement joints and shopfronts below residential blocks alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Alfriston it comes down to the same thing: the right product in a properly prepared joint.
Owners and agents with buildings around smaller places such as Alfriston tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Different surfaces, different methods
Estate-wide resealing programmes
An estate of similar buildings suits a rolling programme. Each block is priced and scheduled in order.
Commercial and mixed-use buildings
Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. We work across portfolios on a planned basis.
What sets the cost
We price every job individually. The things that drive the figure:
- Whether old sealant has to be cut out first
- Access and working height
- How much there is to seal
- Induction, permit and paperwork requirements
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Details that help us quote
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- What the building is and how it’s used
- Any dates the work must fit around
- The product your specification calls for
- Whether an asbestos survey exists
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or email drawings and photos.
Doing it in-house
Redoing a failed joint normally costs more than getting it right at the outset, 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.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Diagnose, treat, sign off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes one or more days per building, depending on the joint lengths and the access, and our waste is bagged and taken away as we go. Smaller jobs around Alfriston can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- 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.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Let building users know which areas are affected
- Send asbestos survey details if the building is pre-2000
- Clear stock, furniture or equipment away from the joints

Common questions from Alfriston clients
Will you take on a block within reach of Berwick (Sussex) station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Can you work at a site such as Berwick Court Farm Business Park, by Alfriston?
Yes. We cover Alfriston and the area around it, including industrial estates, business parks and retail parks such as Berwick Court Farm Business Park. Photos and a short description are enough for a first look.
What guarantee do you give on resealing?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
Can you seal joints high up on a block?
It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Will residents or tenants be disturbed?
We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Leave it or put it right?
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Older rural buildings around Alfriston move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Aftercare for building managers
After handover, a little attention goes a long way:
- Share your contractor requirements early
- Ask residents or tenants to report leaks and draughts early
- Include mastic in your cyclical inspections
- Group repairs into a planned programme
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing.
Looking after buildings in and around Alfriston
Alfriston is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. Central London is about 49 miles from Alfriston. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide.
Landlords with units on estates such as Berwick Court Farm Business Park, 0.9 miles to the north-east of Alfriston, can bring frame, door and external mastic across several units into one programme. Blocks of flats and mixed-use buildings often cluster around stations such as Berwick (Sussex) station, 2.2 miles to the north of Alfriston, and their window and balcony mastic tends to age at the same rate across a building. If you are responsible for a building such as Church of St. Andrew, frame and door mastic needs the same attention as any other property.
