About our mastic sealing in Dormansland
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. If you’re dealing with window mastic that has split and shrunk and patchy repairs in mismatched sealant, we can put it right. For commercial sealant work in Dormansland, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For owners with a single building near Dormansland, we plan to finish in one visit where possible. Send photographs of the frames and joints and we’ll give a fixed quote.
Our workmanship is guaranteed for 12 months, in Dormansland as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- Failed window or door frames, which need a window contractor
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Asbestos-containing sealant, which we don’t remove
If in doubt, ring 01277 525 020 or email the details over and we will say what we think before you book.
Surfaces we seal

What else we do in Dormansland
Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Avoid piecemeal callouts where you can
- Keep bins and bikes away from communal door frames
- Have the asbestos survey to hand for older buildings
- Prioritise elevations facing the weather
Where a paintable product was specified, it can be painted after curing. Silicone usually can’t be painted, so keep decorators off it.
Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
What the job involves on each surface
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Inspecting joints regularly keeps programmes on track.
Window and door perimeters on blocks
Frames vary from uPVC to aluminium and timber, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.
Looking after buildings in and around Dormansland
Rainfall across the South East, Dormansland included, is lower than in many parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first. Dormansland lies roughly 24 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations.
For owners of several units at places like Scanda-Hus Business Park, which lies west of Dormansland, one programme can deal with frame and external mastic across the lot. Older buildings near Dormansland, from historic houses such as Hammerwood Park (to the south-east of Dormansland) to more modest stock, need compatible products when frames are resealed. Blocks of flats and mixed-use buildings often cluster around stations such as Dormans station (to the south-west of Dormansland) and their window and balcony mastic tends to age at the same rate across a building.

What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Backing rod, priming and other preparation
- Which sealant the job calls for
- Site requirements such as inductions and permits
- Travel to remote or island sites
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
What we need to price the job
We can often quote from photographs and a few details. It helps to include:
- The postcode of the building
- The asbestos register, for older buildings
- When you need the work done
- A wide shot and a close-up of the area
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Diagnose, treat, sign off
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself typically taking a few days for most blocks, with larger programmes scheduled building by building. For work around Dormansland, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Preparing the site
- Send your site hours and access windows
- Send any specification or drawings in advance
- For older buildings, check the asbestos register before work

Related advice
Why deal with it now?
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. For buildings around smaller places like Dormansland, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Questions about Dormansland
Does your area include sites such as Scanda-Hus Business Park, near Dormansland?
Yes, sites like Scanda-Hus Business Park are within our area, along with the rest of Dormansland. Photos and a short description are enough for a first look.
Is a smaller place like Dormansland outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
