About our facade sealing in Upper Basildon
Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. Most enquiries involve staining on stone next to old sealant and patch repairs that keep failing, across perimeter joints where frames meet the structure, shopfront frames and coping and flashing joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Upper Basildon it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Construction in and around smaller places such as Upper Basildon is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Work we carry out in West Berkshire comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or use the quote form and we’ll come back to it.

Facades, frames and programmes in Upper Basildon
Upper Basildon is about 45 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. Upper Basildon is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.
Older buildings in the area around Upper Basildon, such as Basildon Park, which lies north-east of Upper Basildon, need care when sealed: the product has to suit soft or historic materials.

Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Record the product and colour used on each elevation
- Combine resealing with other works that need access
- Inspect facade joints on a regular cycle
- Never let anyone seal over old sealant
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it.
Do you need facade sealing in Upper Basildon?
Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.
Any of the following is a good reason to get the joints checked over:
- Draughts around frames and panels
- Failed sealant on precast panel joints
- Previous reseals run over old sealant
- Discoloured or dirty facade joints
Projects at schools like Basildon C.E. Primary School work to term dates, so mastic is programmed tightly.
What your quote should include
- Health and safety accreditation such as CHAS
- The terms of the workmanship guarantee
- Will RAMS and insurance details be available?
- Whether primer will be used where the manufacturer specifies it

Upper Basildon: questions and answers
What documents will you need to give us for a job in Upper Basildon?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
Can you keep pace with our programme in Upper Basildon?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Let us know which documents your site asks for, and we will confirm them alongside the quote.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you seal facades in winter?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Cold, damp mornings can delay a start.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Is old mastic on our building likely to contain asbestos?
In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. We don’t remove asbestos-containing materials.
For managing agents and facilities managers
When you manage a building on behalf of an owner, 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, plus a 12-month guarantee.
We work for building owners and managing agents on everything from one building to a spread of sites around Upper Basildon. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Why deal with it now?
If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. Older rural buildings around Upper Basildon 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.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
