New build and refits around Great Lea Common
The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager. At about 39 miles from central London, Great Lea Common is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.
For a contractor at a hotel such as voco Reading Hotel (0.9 miles north of Great Lea Common), the mastic often has to be finished before a reopening date. With historic properties like Stratfield Saye House (4.3 miles south of Great Lea Common) in the area, refurbishment work often meets old masonry that needs compatible sealants.

Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up. Internal areas can normally carry on while the outside waits. We work on window and door perimeters, brick and block movement joints and internal decorators’ caulk, and what we’re called in for most is existing joints on a refurb that need cutting out and resealing and bath and shower joints scraped during the final clean. For commercial sealant work in Great Lea Common, you deal with one contact from quote to sign-off, whether it’s one building or several.
In the countryside around places like Great Lea Common, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
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 spell out the cover before we begin.

- Joint design decisions that belong to the architect or engineer

Your questions answered
Can you work at a site such as Reading International Business Park, by Great Lea Common?
Yes, sites like Reading International Business Park are within our area, along with the rest of Great Lea Common. A few photographs and the unit address let us price the work.
Is a smaller place like Great Lea Common outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
What accreditations do you hold?
We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. Public liability insurance of five million pounds is in place too.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How do you choose the sealant?
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.
How do you work with the site programme?
We follow the trades through the building. Each plot, floor or elevation is sealed when it’s ready and we tell you if something stops an area being sealed.
Can you work while the building is occupied?
Normally, yes. Phased work can be planned so areas stay in use.
Our process
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For work around Great Lea Common, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- Drawings, the sealant specification and your programme come to us for pricing.
- You receive a fixed quote listing scope, products and phasing.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Every joint is prepared, set to depth and sealed with the specified product.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
What we need from you
- Point out parking and an unloading spot
- Warn occupants and staff about the work
- Tell us your opening times and when work is allowed

Advice

When to call us in Great Lea Common
A joint without backing rod or bond-breaker often fails early. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.
Clients normally get in touch after noticing something like this:
- Internal caulk splitting as the building dries out
- Existing joints on a refurb that need cutting out and resealing
- External joints sealed in damp or cold conditions that are now failing
- Frame gaps too wide for sealant alone
For contractors refurbishing units at places like Reading International Business Park (under half a mile north-east of Great Lea Common), the mastic covers cladding panels, roller-door and window perimeters.
Comparing quotes
- What site paperwork they can supply
- How joint depth will be controlled
- Their plan for phasing and protecting the area
- Whether old or failed sealant will be cut out, not overlaid
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Get the mastic subcontractor involved early in the programme
- Check frame gaps are within the sealant’s range before sealing
- Don’t force external sealing on a damp or frosty day
- Keep product details for future maintenance
After we have sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Holding off until conditions suit avoids callbacks, so we plan external work with that in mind.
How the quote is worked out
These are the things that shape the price:
- Whether the work must be split into stages
- Travel to remote or island sites
- Any access equipment needed
- The total length or number of joints
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.
What to include in your enquiry
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- Whether an asbestos survey exists
- How the joints are reached, and at what height
- What the building is and how it’s used
- Any specification or named product
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or send photos by email.
