On site: what to expect
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. For work around Kingsfold, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Getting the site ready

- Let building users know which areas are affected

Construction mastic for commercial buildings in Kingsfold
Mastic Doctor has been a subcontractor on construction projects for over 20 years. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. For construction mastic on a scheme in Kingsfold, send drawings through our quote form, or phone or email us to talk it through. Most enquiries involve old sealant on a refurbishment that needs stripping before new work and snag items on joints that need redoing before handover, on floor and skirting junctions, window and door perimeters and cladding and panel joints. Facilities teams, main contractors and managing agents in Kingsfold tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Conversions of older rural buildings near smaller places such as Kingsfold 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 usually what’s needed.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

When it isn’t the sealant
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Joints damaged after sign-off by following trades
- Oversized gaps that need packing or adjustment by others
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
Surfaces we seal
- Sanitary and kitchen joints
- Cladding and panel joints
- Internal decorators’ caulk
- Brick and block movement joints
- Window and door perimeters
- Floor and skirting junctions
How the job changes by surface
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly and baths are loaded where appropriate before sealing.
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. Depth is controlled with backing rod so the bead bonds to two sides only.

Maintenance after handover
For the best life from the joints:
- Release areas for mastic once other trades have finished in them
- Don’t force external sealing on a damp or frosty day
- Stick to the specified sealant rather than a generic substitute
- Record the products used in the O&M file
Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out, and avoids a rush.
Construction mastic in Kingsfold: the local picture
Kingsfold is about 28 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme. Kingsfold is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.
New wings at hospitals like Horsham Hospital (3.2 miles south of Kingsfold) bring long runs of window and panel joints to seal. Units on estates such as Northlands Business Park (to the west of Kingsfold) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Kingsfold is about 3 miles north of Horsham, in West Sussex. Any commercial site in Kingsfold is covered, for single jobs and planned programmes alike. Our West Sussex coverage takes in 373 places. We also cover Brighton, some 21 miles away.
We take on mastic packages across the RH12 postcode area. Among the streets we cover are Foxwood, Priors Wood and Dorking Road, and sites on any of them can send details for a fixed quote. If your building is just outside Kingsfold, we cover Paynes Green (2 miles north-west), Capel (2 miles north), Ockley (3 miles north-west), Forest Green (4 miles north-west) and Beare Green (4 miles north). A short drive away, we cover Crawley (6 miles east), Horsham (3 miles south), Haywards Heath (13 miles south-east), Burgess Hill (14 miles south-east), East Grinstead (14 miles east) and Broadfield (6 miles east).
Near you in Kingsfold
Recent enquiries here include premises near The Dog and Duck Public House and the streets around them. For rail, the closest station is Warnham station, roughly 1.6 miles south of the centre. Other landmarks nearby include Horsham Hospital (3.2 miles south). Not far away are Leith Hill and Vann Lake.
Doing it in-house
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.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Why it’s worth doing now in Kingsfold
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go and saves applicators coming back again and again. Snagging can be priced as a separate stage. Around Kingsfold, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
Why appoint us
- Specification-led, product-correct work
- Fully insured
- A fixed quote before work starts
- A Constructionline member, so easy to vet

Kingsfold: questions and answers
Can you take on a job at a hospital such as Horsham Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Kingsfold too small for you to travel to?
Not at all. Kingsfold is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on mastic snagging only?
Yes. Share the list and photographs, and a fixed quote follows, then clear it to your programme.
Are you CHAS accredited?
We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We’re also fully insured, with five million pounds of public liability cover.
Do you do fire-rated sealing on new builds?
Fire-rated sealing at service penetrations and linear gaps can be included where specified. Tell us what records you need and we will confirm with the quote.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
