What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Joint design decisions that belong to the architect or engineer
- Frames fitted out of tolerance
- Defective windows, doors or glazing units (the supplier or installer’s job)

Construction mastic in Horley
Mastic Doctor has been a subcontractor on construction projects for over 20 years. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. For construction mastic on a scheme in Horley, send drawings through our quote form, or phone or email us to talk it through. If you’re dealing with frame perimeters left unsealed or poorly sealed and inconsistent sealant finishes from plot to plot, we can put it right, on cladding and panel joints, sanitary and kitchen joints and floor and skirting junctions alike. Whoever orders the work in Horley, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Many towns of Horley’s size have older buildings being converted or extended, which puts new frames and panels against old brick, stone or render. Getting the product and primer right for both faces is what keeps those joints sound.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What affects the price in Horley
A fixed quote reflects the actual work. It takes account of:
- How much existing material needs removing
- The size and state of each joint
- Which sealant the job calls for
- Any access equipment needed
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Sending details for a quote
For an accurate fixed quote, we need a clear picture of the site. Send us:
- The asbestos register, for older buildings
- Drawings or a marked-up plan, if available
- When you need the work done
- How the joints are reached, and at what height
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. If you have questions first, give us a call on 01277 525 020 or email a schedule or drawings.
Looking after the joints
A few simple habits keep the new joints working:
- Flag uneven or tapered frame gaps early
- Keep finished joints away from paint, plaster and scrapers
- Ask for joint and product checks before the package is urgent
- Record the products used in the O&M file
A new structure shifts as it loses construction moisture. The right product in each joint copes with that while rigid fillers and caulk can crack where movement is larger. We can advise if a joint needs a different product.
External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work, so we plan external work with that in mind.
From enquiry to sign-off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. Town-centre premises in Horley may have limited parking, so tell us what’s nearby. Industrial and business units usually have yard or car park space.
- We start with the drawings, specification and programme.
- Quantities are measured and a fixed price returned.
- We agree with the site team which areas come first.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
Preparing the site
- Share your working hours and any access restrictions
- Tell us what induction or permit system the site runs
- Send any specification or drawings in advance
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

New build and refits around Horley
Horley lies roughly 22 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. Horley sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.
For contractors refurbishing units at places like Gatwick Business Park, which lies south-west of Horley, the mastic covers cladding panels, roller-door and window perimeters. Extensions at sites like Spire Gatwick Park Hospital (Private), 1 mile to the south-west of Horley, usually sit beside working departments, and the mastic follows strict access rules. Work at a hotel such as Days Hotel (0.6 miles north-east of Horley) tends to be programmed around bookings, mastic included.

Common questions from Horley clients
Is hospital work, at somewhere like Spire Gatwick Park Hospital (Private), something you do?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Can the mastic package for our job in Horley follow the site programme?
Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
What do you charge?
There isn’t a price list, as every site differs. Send photographs or drawings and we’ll price it at a fixed figure.
How many days will you need on site?
That varies with the scale of the job, but the work normally takes a day or two on a small fit-out and several weeks on a large multi-storey package. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can you handle several sites?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Different surfaces, different methods
Snagging before handover
Snagging is often the final mastic stage. We can work through the snag list area by area.
External facade and movement joints
Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it.
Owners, agents and contractors
Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
