When to call us in Theydon Garnon
UV and rain age external sealant. It stiffens, stops stretching and cracks, especially on south and west faces.
Any of the following is a good reason to get the joints checked over:
- Draughts at frames across a block
- No planned programme for sealant
- Old repairs sealed over failed mastic
- The same joint failures repeated across a portfolio
With historic buildings such as Hill Hall (1.2 miles east of Theydon Garnon) in the wider area, owners of older properties around Theydon Garnon should expect mastic to need a product that suits old masonry.

Mastic sealing in Theydon Garnon, done properly
Before work starts, most agents and landlords want the documents in order. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are a Constructionline member and CHAS accredited, and we carry public liability insurance. Most enquiries involve window mastic that has split and shrunk and failed external movement joints, across external wall and movement joints, communal entrances and stairwells and window and door perimeters on blocks. Most enquiries from Theydon Garnon start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Around smaller places like Theydon Garnon, 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.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why deal with it now?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once and is simpler to manage and budget. Converted and older buildings near places like Theydon Garnon tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Pricing mastic joints depends on quantities, condition and access. Ask us for a fixed quote.

Block-wide mastic in Theydon Garnon
At about 15 miles from central London, Theydon Garnon is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Theydon Garnon is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
For a school such as Theydon Bois Primary School, perimeter mastic on windows and doors is a holiday job. Trustees of buildings like Church of All Saints can bring frame and external mastic into a planned maintenance list.

Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Maintenance after handover
After handover, these steps help:
- Prioritise elevations facing the weather
- Make mastic part of routine maintenance checks
- Check the asbestos register before any old mastic is disturbed
- Share your contractor requirements early
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.

Questions we’re asked in Theydon Garnon
Is Hobbs Cross Business Centre, near Theydon Garnon, within your area?
Yes. Estates, retail parks and business parks around Theydon Garnon, Hobbs Cross Business Centre among them, are all within reach. To start, just give us a call on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Is Theydon Garnon too small for you to travel to?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you take on resealing for a block portfolio?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place and we’ll confirm the approach in the quote.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
How do I request a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or send photos by email. Include photographs or drawings if you have them.
