Questions we are asked in Lower Green
Is Stype Business Centre, near Lower Green, within your area?
Yes. We cover Lower Green and the area around it, including industrial estates, business parks and retail parks such as Stype Business Centre. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is a smaller place like Lower Green outside your area?
Not at all. Lower Green is within our area. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Do we need an asbestos check before resealing?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed. Removal of asbestos isn’t something we do.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Do you provide access for facade work?
That varies with the building and the access on offer. Share what access exists or is planned when you send details.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Facade sealing in Lower Green
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure. Where sealant is the specified fix, we also take on coping and flashing joints. Most enquiries involve failed sealant on precast panel joints and hard, chalky sealant that no longer flexes, on window and door perimeters, perimeter joints where frames meet the structure and stone and brick facade joints. Facilities teams, main contractors and managing agents in Lower Green tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Lower Green, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Don’t wait for a second leak before calling
- Share access with other external trades
- Keep the sealant details on the building file
- Confirm the survey covers external sealants in older buildings
Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal without guesswork.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.
When to call us in Lower Green
The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.
Most enquiries start with something like this:
- Staining on stone next to old sealant
- Perimeter sealant that has split or peeled away
- Gaps between rainscreen or cladding panels
- Perimeter joints where frames meet the structure
Recladding or extending a unit at a site like Stype Business Centre (2 miles west of Lower Green) brings panel joints and frame perimeters into the programme.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- Will CSCS-carded applicators be on site?
- Can the work be phased to keep areas open?
- What the guarantee covers, and for how long
Why act early in Lower Green
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. Older rural buildings around Lower Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What you get with us
- Matching to RAL references, product permitting
- A Constructionline member, so easy to vet
- Public liability insurance in place
- Specification-led, product-correct work

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Lower Green can form part of a wider programme across West Berkshire.

Mastic packages on Lower Green sites
Lower Green is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. Central London is about 61 miles from Lower Green. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.
Historic houses such as Stargroves (to the south-east of Lower Green) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. For contractors at a school such as Inkpen Primary School, sealing has to be finished before term starts.
