Planned mastic for Lenham Forstal portfolios
Central London is about 41 miles from Lenham Forstal. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. Lenham Forstal 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.
Student blocks close to universities like Canterbury Christ Church University (to the north-west of Lenham Forstal) are easiest to work on between tenancies. Older community buildings, Church of the Holy Trinity among them, often have frames of mixed ages whose mastic varies.

How we handle mastic sealing in Lenham Forstal
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. We work on communal entrances and stairwells, window and door perimeters on blocks and external wall and movement joints, and the failures we’re asked to look at most are leaks at window and door perimeters and repeated reactive repairs to the same buildings. Most enquiries from Lenham Forstal start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Owners and agents with buildings around smaller places such as Lenham Forstal tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Leave it or put it right?
A bead run over old mastic can look like a repair. It doesn’t bond and usually fails within a short time. Cutting out and resealing properly does it once. Converted and older buildings near places like Lenham Forstal tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Reduce knocks to communal area joints
- Plan resealing building by building rather than complaint by complaint
- Share your contractor requirements early
- Log resealing dates block by block
Keep records of when each building was resealed. It helps plan the next round and shows what was done.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and the complaints that come with it.

Signs you need mastic sealing in Lenham Forstal

Most enquiries start with something like this:
- Occupiers reporting cold air round windows
- The same joint failures repeated across a portfolio
- Patchy repairs in mismatched sealant
- Damaged joints in communal entrances and corridors
If your remit includes a building such as The Lenham School, frame and door mastic can be programmed for the holidays.

Your questions answered
We manage a building near Lenham station. Can you help?
Yes. Blocks of any size are within what we do. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Lenham Forstal too far out for you?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
How do you handle work on occupied blocks?
Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so it can be arranged.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
