In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Can you quote from photographs?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
About our construction mastic in Horley
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. If you’re dealing with internal caulk splitting as the building dries out and window and door perimeters that won’t pass inspection, we can help. Facilities teams, main contractors and managing agents in Horley tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Construction in and around smaller places such as Horley is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

When to bring in a specialist
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
New build and refits around Horley
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, so we time external mastic for dry faces and agree it with the site team. At about 69 miles from central London, Horley is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
Work at a hotel such as Wroxton House Hotel (to the south of Horley) tends to be programmed around bookings, mastic included. New units and refits on sites such as Alkerton Oaks Business Park, 2.4 miles west of Horley, need their panel and perimeter joints sealed to the specification. When a school such as North Oxfordshire Academy is extended or refurbished, the mastic package is often squeezed into the holidays.
Horley is about 3 miles north-west of Banbury, in Oxfordshire. Across the OX15 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Leave it or put it right?
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 avoids repeated visits. Snagging can be priced as a separate stage. Halls, stores and units around places like Horley may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Approving fire stopping as compliant
- Damage to finishes by other trades after we have sealed
- Faulty frames rather than failed sealant
If you’re not sure, just call the office on 01277 525 020 or email us and we will give you a straight answer before you book.

After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Allow flexibility for external sealing in damp or cold weather
- Keep product details for future maintenance
- Ask installers to correct oversized gaps first
- Stick to the specified sealant rather than a generic substitute
Expect some settlement in the first months. Flexible sealants in the right joints handle normal movement while rigid fillers and caulk can crack where movement is larger. We can advise if a joint needs a different product.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes, and our waste is bagged and taken away as we go. If others near Horley need work, visits can be combined. A fixed quote is given before anything starts.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Before we start on site
- Point out any areas we must not close
- Send your site hours and access windows
- Flag any permit to work we will need
