Doing it in-house
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
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.
Construction mastic in Headley, done properly
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over, so applicators arrive when areas are genuinely ready. Sealing too early only means coming back once others have damaged it. If you have different trades sealing to different standards and missed perimeter joints on a new elevation, we can help, whatever the surface. A single leaking joint is often how a building in Headley 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 Headley, building work typically 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.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Faulty frames rather than failed sealant
- Approving fire stopping as compliant
- Joints damaged after sign-off by following trades
Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly.
Joints and surfaces we work on
- Internal decorators’ caulk
- Brick and block movement joints
- Floor and skirting junctions
- Cladding and panel joints
- Window and door perimeters
- Sanitary and kitchen joints
What sets the cost
What shapes the price:
- How much there is to seal
- Access and working height
- How much existing material needs removing
- Specialist products, such as fire-rated or hygienic sealants
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- When you need the work done
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
- Clear photos of the problem areas
Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. If you have questions first, give us a call on 01277 525 020 or send photos by email.
Leave it or put it right?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. Sound frames often need only a new perimeter seal and that’s a far smaller job. We will say so if a frame itself is the problem. One visit to deal with every failing joint makes more sense than several trips to a place like Headley. Photos of every joint help us quote for the whole job.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.
What you get with us
- Colour options checked against the specified product
- Colours chosen to suit frames, cladding or finishes where possible
- Fixed quotes based on photos, drawings or a visit
- Constructionline member for supplier checks

New build and refits around Headley
Rainfall across the South East, Headley included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. Headley is about 41 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
New wings at hospitals like Chase Hospital, 1.9 miles to the south-west of Headley, bring long runs of window and panel joints to seal. School extensions, at buildings such as The Holme Church of England Primary School, normally run to the summer holidays, mastic included. Recladding or extending a unit at a site like Passfield Industrial Estate (1.1 miles south of Headley) brings panel joints and frame perimeters into the programme.
Headley is about 6 miles south of Farnham, in Hampshire. Any commercial site in Headley is covered. Headley is one of 723 places in Hampshire on our list. We also cover Portsmouth, around 24 miles from Headley.
Commercial sites across GU35 are covered for mastic packages. Streets here include High Street, Crabtree Gardens and Pound Close, and sites on any of them can send details for a fixed quote. Just outside Headley, we also work in Arford (1 mile north-east), Headley Down (1 mile east), Lindford (1 mile west), Standford (1 mile south-west) and Deadwater (1 mile west). Further afield, our area takes in Farnborough (12 miles north), Fleet (11 miles north), Aldershot (9 miles north), Alton (7 miles west), Petersfield (9 miles south-west) and Yateley (15 miles north).
Local landmarks in Headley
Around Headley, our work takes us to commercial buildings near Mill Chase Academy and The Holly Bush Inn and the streets around them.

For a walk, there’s Deadwater Valley and Wheeler's Down.
Questions about Headley
Is Headley too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can you take on a job at a hospital such as Chase Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you clear a mastic snag list before handover?
Yes, we can. Send the snag list or photos and we’ll price it, with the work timed to your handover date.
Can you work while the building is occupied?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Aftercare for building managers
A few simple habits keep the new joints working:
- Bring the mastic contractor in after the last trades are through
- Get the mastic subcontractor involved early in the programme
- Plan external elevations with the weather in mind
- Check frame gaps are within the sealant’s range before sealing
Our 12-month guarantee covers the workmanship from sign-off. Damage by others isn’t a workmanship fault, so protecting sealed areas matters.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Getting the product and preparation right first time avoids that.
Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. Rural sites near Headley may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- 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.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Share the asbestos register for older buildings
- Send any specification or drawings in advance
