Why act early in Sedrup
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects and external joints are where it shows first. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Converted and older buildings near places like Sedrup tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Construction mastic in Sedrup, done properly
The specification and the programme set the job. If a product is named, that’s what goes in; any alternative we suggest is put to you before anything changes. Backing, primer and depth follow what the sealant maker sets out so the detail on the drawing is what ends up on site. Most enquiries involve sanitary sealant damaged by following trades and a long mastic snag list close to completion, on internal decorators’ caulk, brick and block movement joints and floor and skirting junctions. A single leaking joint is often how a building in Sedrup first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Sedrup, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
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.

Questions we’re asked in Sedrup
Is Fountain Business Centre, near Sedrup, within your area?
Yes. Our area takes in Sedrup and its surroundings, with estates and business parks such as Fountain Business Centre included. Photos and a short description are enough for a first look.

Do your applicators hold CSCS cards?

Can you clear a mastic snag list before handover?

Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Are you insured?
Yes. We are fully insured, including public liability cover.
Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Allow flexibility for external sealing in damp or cold weather
- Protect sealed areas from following trades
- Share drawings and the specification as soon as possible
- Use the product the specification names
Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead.
A missed perimeter seal on one window can wet the reveal and the plaster inside. That usually means redoing finishes in a completed area and possibly a delayed handover. A check of every frame before decorators start is worth the time.
Building and refurbishing in Sedrup
Sedrup 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. The area within 2 miles of Sedrup holds a number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

On a campus such as University Campus Aylesbury Vale, which lies north-east of Sedrup, new teaching buildings and residences are usually built and refurbished around the academic year.

Site staff or a sealant specialist?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
What the job involves on each surface
Window and door perimeters
Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. We follow what’s specified, and colour-matched products can be used where the frame is on show.
Internal decorators’ caulk
Caulk is easy to apply badly. Done properly, it saves decorators time and gives a clean line and keeps the snag list down.
