Surface by surface
Commercial kitchens and tea points
In kitchens, sealant lines at worktops, sinks and wall panels take heat, grease and daily cleaning. Proper degreasing comes before any new sealant, with a food-safe or hygienic product wherever food contact can happen.
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. The lasting answer is removal, preparation and a new sanitary bead, room by room if that suits the building.
Sealant applicators in New Forest
Commercial occupiers rarely want a floor out of action for sealant work. Tell us your site hours and access windows and we will plan around them; phased work can also be planned so areas stay in use. That applies whether the building is an office, a shop, a hotel, a college or a care home. Site teams most often ask us about frame sealant that has cracked, shrunk or pulled away and smeared sealant across finishes from a rushed job, across washrooms and tea points, window and door perimeters and external facade joints.

In an occupied building in New Forest, the job is planned so areas stay in use: we agree the order with you and hand back each area with its cure time.
Rural business units near smaller places such as New Forest 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 by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What New Forest’s businesses ask us to seal
Rainfall across the South East, New Forest included, is lower than in many parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.
For any commercial premises in New Forest, a lasting joint depends on full removal of the old sealant and clean, dry faces.

FAQs: New Forest
Which documents can you supply for work in New Forest?
RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Is a smaller place like New Forest outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
How do we get a quote?
Send what you have, even a few photos and rough lengths. We follow up with questions or a visit where needed, then a fixed quote.
Can you handle sealant work across several sites?
Yes, within the areas we cover: South East England, Greater London and Scotland. One contact and one process for every building makes a portfolio easier to manage.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we will price the work to it.
What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- A failed roof covering or waterproofing membrane
- A dripping trap, valve or pipe behind a fitting
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
If in doubt, call 01277 525 020 or send details through our quote form and we’ll say what we think.
Joints and surfaces we work on
- Window and door perimeters

How a job runs
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Jobs in and around smaller places like New Forest are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First, details reach us through the quote form or a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
Before we start on site
- Make sure the joints can be reached
- Share your working hours and any access restrictions
- Point out any areas we must not close
Getting a fixed quote

Advice
For managing agents and facilities managers
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
Do you need commercial sealant contractors in New Forest?
Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed will all fail early. BS 6213 gives guidance on choosing construction sealants.
What tends to prompt an enquiry:
- Frame sealant that has cracked, shrunk or pulled away
- Messy, uneven beads from earlier work that let the building down
- Shrunken sealant along kitchen worktops and splashbacks
- Sanitary sealant that has gone black and patchy
Colour matters on frontages and fit-outs, so the quote confirms which colours the chosen product comes in.
Before you book anyone
- Proof of insurance
- How the joint faces will be prepared and primed
- The named product and why it was chosen
- Will CSCS-carded applicators be on site?
What sets the cost
Your fixed quote is built from the real scope. It allows for:
- Working within restricted access windows
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
Details that help us quote

- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
- Specification clauses that apply
- Access details, including height
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email a schedule or drawings.
