Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Our process
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Rural sites near Penn may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- You send photos, drawings or a list of the joints and areas involved.
- We work out why the joints have failed and fix a quote for the agreed scope.
- Site hours, access windows and the order of areas are agreed before we start.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- Finished joints are checked with you and handed over with our 12-month guarantee.
Getting the site ready
- Flag any permit to work we will need
- Explain the parking and delivery arrangements
- Let building users know which areas are affected
Getting a fixed quote
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

About our commercial sealant contractors in Penn
On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey, since managing asbestos is the dutyholder’s responsibility. If a material is suspected, work stops until it’s tested (removing asbestos-containing materials isn’t something we do). Site teams most often ask us about a top-up bead over failed sealant, now lifting and expansion joints with the sealant torn out, on movement joints in walls and floors, washrooms and tea points and kitchen worktops and splashbacks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Penn, that means joint design, primers and backing rod as standard.
In Penn, as anywhere, the first joints to go are typically the ones that work hardest: south-facing perimeters, entrance thresholds and busy washrooms.
Rural business units near smaller places such as Penn are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

How the job changes by surface
Movement joints in walls and floors
Movement joints in walls and floors let the structure expand and contract. Failed seals let grit and water in, and the edges start to suffer. The joints are resealed using a sealant matched to the movement and any traffic.
Facade and cladding joints
Facade sealant failures can be hard to spot from the ground. Close-up photographs or a site visit tell us what’s needed, and we will confirm the colours available for the specified product.
Leave it or put it right?
Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. In many cases the element is fine and only the seal around it has given up. A careful reseal is a far smaller undertaking than replacement. Around Penn, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
Why appoint us
- One phone line for London, the South East and Scotland
- A range of standard colours, depending on the product
- Fixed quotes based on photographs, drawings or a visit
- A Constructionline member, so easy to vet
Cost factors for sealant joints
Each job is priced on its own details. The things that drive the figure:
- Travel to remote or island sites
- How accessible the joints are
- How much existing material needs removing
- The product specified
The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.
What to include in your enquiry
However big the job, the same details help:
- What the building is and how it’s used
- The asbestos register, for older buildings
- Specification clauses that apply
- Anything awkward about access or site hours
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email drawings and photos.
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. A poor seal in places like these tends to cost more to put right later.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
After the work
Problems stay small when the joints are checked regularly. In particular:
- Note dates and locations of sealant work for future planning
- Put external and wet-area joints on a regular inspection round
- Keep washroom and kitchen extraction working
- Don’t let cleaning or traffic back on before the cure time is up
Brief your cleaning team on the joints that have been resealed. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces; a mild cleaner is all most joints need.
A failed external joint lets water in every time it rains. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Resealing early keeps the problem in the sealant and out of the building.

Central London is about 27 miles from Penn. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. If you have premises across the region, one contractor can cover them all. The 3 miles around Penn take in at least three named trading estates, business parks or retail parks. Sites like these see regular refits, with shopfronts, offices and staff areas to seal.
Units at places like Wycombe Retail Park, 1.5 miles south-west of Penn, are refitted as brands change, and the joints have to suit each new scheme. If you have premises on more than one site, say at Peregrine Business Park and Tannery Road Industrial Estate, one contractor and one quote can cover both. For premises near High Wycombe station, 2.1 miles to the west of Penn, footfall is part of the plan: work is phased so shops and offices keep trading.

Penn: questions and answers
Is a smaller place like Penn outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Can you match sealant colours for premises in Penn?
Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.
What about asbestos in old mastic?
Some older mastics did contain asbestos. So we check the register first and stop work on anything suspect until it’s tested. HSE guidance on asbestos is a useful reference.
How many days will you need on site?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
What site paperwork can you provide?
Send your site requirements with the enquiry. For older buildings we’ll ask for the asbestos register, plus your site induction rules.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
