FAQs: Gaston Green
Is Gaston Green too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Does your area include sites such as Spellbrook Business Centre, near Gaston Green?
Yes. Our area takes in Gaston Green and its surroundings, with estates and business parks such as Spellbrook Business Centre included. Send details of the unit and the work through our quote form for a quick quote.
Can the building stay open while you work?
Typically, yes. Phased work can be planned so areas stay in use.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
Do you guarantee your work?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.
What’s the quickest route to a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
About our facade sealing in Gaston Green

Common problems we fix in Gaston Green
When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and movement soon pulls it away.
Site and facilities staff are often the first to spot these:
- Perimeter joints where frames meet the structure
- Old perimeter mastic that has dried out
- Patch repairs that keep failing
- Cladding panel joints that have opened up
New units and refits on sites such as Spellbrook Business Centre (0.6 miles north-west of Gaston Green) need their panel and perimeter joints sealed to the specification.

Why act early in Gaston Green
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. One visit to deal with every failing joint makes more sense than several trips to a place like Gaston Green, rather than one at a time. Photos of every joint help us quote for the whole job.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Movement beyond what any sealant can handle
- Work on the window or framing system itself
- Render or concrete edges that have broken away
Not sure which it is? You can ring 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Quoting for work in Gaston Green
Quotes vary with the job. Expect it to depend on:
- The product specified
- How much there is to seal
- Working within restricted access windows
- How much existing material needs removing
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- Where the site is, with the postcode
- Rough lengths or quantities, or drawings if you have them
- Specification clauses that apply
- Photos of the joints, close up and from further back
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or use the quote form if you’d rather talk the job through.
From enquiry to sign-off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. If others near Gaston Green need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We start with photographs, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Preparing the site
- Send your site hours and access windows
- Point out any areas we must not close
- Send any specification or drawings in advance
Getting a fixed quote

Related advice
After the work
After handover, a little attention goes a long way:
- Brief window cleaners about newly sealed joints
- Never let anyone seal over old sealant
- Share access with other external trades
- Add perimeter sealant to planned maintenance checks
Record the sealant type and date on the building file. Future work can then match the product and colour across the elevation.
Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail instead of after the damage.
Mastic packages on Gaston Green sites
Rainfall across the South East, Gaston Green included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. Gaston Green is about 26 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.
When a school such as Spellbrook CofE Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. On a healthcare site such as Rivers Hospital (2.3 miles south-west of Gaston Green), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
