Sites and facades in and around Etchingham
Rainfall across the South East, Etchingham included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 41 miles from Etchingham. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.
With historic properties like Bateman's, 2.8 miles south-west of Etchingham, in the area, refurbishment work often meets old masonry that needs compatible sealants. For contractors at a school such as Etchingham Church of England Primary School, sealing has to be finished before term starts.

Construction mastic for commercial buildings in Etchingham
Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list, and every return visit costs time. Our aim is joints that pass at the first inspection. We work on sanitary and kitchen joints, cladding and panel joints and window and door perimeters, and the failures we’re asked to look at most are window and door perimeters that won’t pass inspection and early adhesion failures on new external joints. Searching for sealant specialists in Etchingham? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Conversions of older rural buildings near smaller places such as Etchingham bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Bring the mastic contractor in after the last trades are through
- Ask for joint and product checks before the package is urgent
- Stick to the specified sealant rather than a generic substitute
- Don’t force external sealing on a damp or frosty day
Expect some settlement in the first months. The right product in each joint copes with that. We can advise if a joint needs a different product.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure, so the installer needs to correct it first. We raise them during our first walk of the area.
When to call us in Etchingham
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with. Better to raise it at the start than seal a joint that’s bound to fail.
These are often picked up first by site or facilities staff:
- Existing joints on a refurb that need cutting out and resealing
- Cracks opening in caulked internal joints
- Perimeter gaps outside the sealant’s range
- Different trades sealing to different standards
On a healthcare site such as Ticehurst House Hospital, which lies north-west of Etchingham, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Before you book anyone
- Which product they’ll use, and why it suits the joint
- Health and safety accreditation such as CHAS
- Will failed sealant be removed rather than covered?
- How joint depth will be controlled
Work for main contractors and building owners
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Different surfaces, different methods
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s paintable and suits gaps that don’t move.
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. We use the specified perimeter sealant, usually a low-modulus neutral-cure silicone and set the depth with backing where needed.
Common questions from Etchingham clients
Is Parsonage Farm Business Centre, near Etchingham, within your area?
Yes, sites like Parsonage Farm Business Centre are within our area, along with the rest of Etchingham. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Is a smaller place like Etchingham outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work to our specification?
The specified product is what goes in. Any suggested alternative is put to you before anything changes.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
How long does a typical visit take?
That varies with the scale of the job, but the work normally takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. For bigger or phased jobs, we will set out a timescale with the quote.
Do your applicators hold CSCS cards?
CHAS and Constructionline are both in place, and each applicator is CSCS-carded. Public liability insurance is in place.
From enquiry to sign-off
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. Jobs in and around smaller places like Etchingham are normally planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Send any specification or drawings in advance
- Warn occupants and staff about the work
- Share your working hours and any access restrictions

When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Joints damaged after sign-off by following trades
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Frame gaps too wide for sealant, which the installer needs to correct
If you’re not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
