How a job runs
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. If you have more than one building in Dorking, they can often be done on the same visit, with one quote covering them. Give us your access times and we’ll fit the work in.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
Preparing the site
- Share the asbestos register for older buildings
- Tell us your opening times and when work is allowed
- Confirm the product named in the specification
Quotes
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Mastic sealing in Dorking, 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’re a Constructionline member and CHAS accredited, and we carry public liability insurance. Most enquiries involve brittle perimeter mastic across a building and movement joints with sealant missing, on communal entrances and stairwells, shopfronts below residential blocks and balcony and threshold joints. Most enquiries from Dorking 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.
In a town such as Dorking, buildings managed by agents and landlords range from flats over shops to small blocks and offices. Window and door perimeters, external joints and communal areas all need their mastic renewed from time to time.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Leave it or put it right?
Looking at mastic during planned maintenance costs little. Leaving it until there’s a leak turns it into reactive work and less choice about when. For businesses and landlords in Dorking, a tidy, sound joint also matters for appearance. Fresh sealant makes a building look maintained.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Questions about Dorking
Can you quote for a block close to Dorking Deepdene station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Can you work in a care home near Dorking with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.
Do you cover Dorking?
Yes. Dorking is in our area. To discuss a job, give us a call on 01277 525 020 or email the details over.
How long does a typical visit take?
It depends on the scope, but the work usually takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we will set out a timescale with the quote.
Can you send RAMS and CSCS details before starting?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Misted or failed double-glazed units
- Masonry that has broken away beside the joint
Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly.
Surfaces we seal
- Balcony and threshold joints
- Shopfronts below residential blocks
- Window and door perimeters on blocks

Cost factors for mastic joints
Each job is priced on its own details. The main factors are:
- How accessible the joints are
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
- The size and state of each joint
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Before you send an enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Specification clauses that apply
- A wide shot and a close-up of the area
- Where the site is, with the postcode
- Any dates the work must fit around
Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, ring 01277 525 020 or email drawings and photos.
Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Blocks and managed buildings in Dorking
At about 21 miles from central London, Dorking is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate. Dorking is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
Buildings close to stations like Dorking Deepdene station, 0.6 miles north of Dorking, are often flats over shops, with frame mastic to keep sound. Churches, halls and community buildings such as Church of St Paul are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Older buildings near Dorking, from historic houses such as Polesden Lacey, 2.7 miles north-west of Dorking, to more modest stock, need compatible products when frames are resealed.
