Mastic sealing in Guestling Green, done properly
Managing agents and housing associations typically need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. If you are dealing with patchy repairs in mismatched sealant and no planned programme for sealant, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Guestling Green is the same: the right product in a properly prepared joint.
Around smaller places like Guestling Green, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or use the quote form and we will arrange a return visit.

Why deal with it now?
Draughts round window perimeters cost occupiers comfort and the windows usually get the blame. In many cases, new perimeter sealant deals with it when the frames themselves are sound. Halls, stores and units around places like Guestling Green may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Why us?
- Clear, fixed quotes

Site staff or a sealant specialist?
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Our process
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Guestling Green need work, visits can be combined. A fixed quote is given before anything starts.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.
Preparing the site
- Flag any permit to work we’ll need
- Point out parking and an unloading spot
- Confirm the product named in the specification

Advice
Guestling Green: questions and answers
Will you take on a block within reach of Three Oaks station?
Yes, and several blocks can go on one quote. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Can being near the sea in Guestling Green affect the sealant we need?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
How do you reach windows on upper floors?
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.

What else we do in Guestling Green
For owners and agents in Guestling Green
Guestling Green sits close to the coast, within about 2 miles. On buildings near the shore, the side facing the weather usually needs its mastic renewed first. Guestling Green sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
Schools and community buildings such as Guestling Bradshaw Church of England Primary School need frame and external mastic kept sound like any building. Blocks of flats and mixed-use buildings often cluster around stations such as Three Oaks station (1.1 miles north-west of Guestling Green) and their window and balcony mastic tends to age at the same rate across a building. If you own or manage units on a site such as Ivyhouse Industrial Estate (1.8 miles south-west of Guestling Green), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

What sets the cost
Your fixed quote is built from the real scope. It allows for:
- Access and working height
- Quantities, in metres or numbers
- Whether old sealant has to be cut out first
- Location, for remote and island sites
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- Photos of the joints, close up and from further back
- Whether the building will be occupied during the work
- Asbestos survey details if the building is older
- Approximate linear metres or a joint schedule
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or send photos by email.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Make mastic part of routine maintenance checks
- Protect low-level joints in entrances
- Have the asbestos survey to hand for older buildings
- Make it easy for occupiers to report draughts
Keep records of when each building was resealed. That makes future programmes easier to plan and gives you a history.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.
Different surfaces, different methods
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and spreads the work.
