About our construction mastic in Forest Row
Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. If you have failed sealant in an existing building being refurbished and early adhesion failures on new external joints, we can put it right, on floor and skirting junctions, brick and block movement joints and sanitary and kitchen joints alike. Facilities teams, main contractors and managing agents in Forest Row tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Building work in places the size of Forest Row is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done 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.

Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

How the quote is worked out
Before we quote, we look at:
- Which sealant the job calls for
- How much there is to seal
- Phasing around occupants
- The site’s rules and procedures
A quote for mastic packages depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.
What to include in your enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Any specification or named product
- Your programme or deadline
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. For a chat about it beforehand, ring 01277 525 020 or email the details over.
When something else is needed
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Joint design decisions that belong to the architect or engineer
- Oversized gaps that need packing or adjustment by others
- Deciding which fire-stopping product a penetration needs
If you’re not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer.
What we seal
- Brick and block movement joints
- Floor and skirting junctions
- Internal decorators’ caulk
- Window and door perimeters
- Sanitary and kitchen joints
- Cladding and panel joints
Do you need construction mastic in Forest Row?
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Site and facilities staff are often the first to spot these:
- Missed perimeter joints on a new elevation
- Old sealant on a refurbishment that needs stripping before new work
- Early adhesion failures on new external joints
- A long mastic snag list close to completion
Historic houses such as Standen, 2.3 miles west of Forest Row, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Mastic packages on Forest Row sites
The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. At about 29 miles from central London, Forest Row is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.
New wings at hospitals like Queen Victoria Hospital, 3.2 miles to the north-west of Forest Row, bring long runs of window and panel joints to seal. School extensions, at buildings such as Forest Row Church of England Primary School, typically run to the summer holidays, mastic included.
Forest Row is about 3 miles south-east of East Grinstead, in East Sussex. Our applicators travel to Forest Row for work on mastic packages, handled exactly as we handle every other area.

Your questions answered
Is hospital work, at somewhere like Queen Victoria Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Forest Row too small for you to travel to?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Are you fully insured?
Yes. We’re fully insured, and the certificate can go with your quote.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
Are you CHAS accredited?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. Tell us what site paperwork you need and we’ll confirm with the quote.
How do I request a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or send photos by email. Include photos or drawings if you have them.
From enquiry to sign-off
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a site in Forest Row, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- 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.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Clear stock, furniture or equipment away from the joints
- Have the specification and drawings to hand

External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer.
