Construction mastic for businesses in Steep
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What sets the cost
The price varies from site to site. Expect it to depend on:
- Access and working height
- The total length or number of joints
- Travel to remote or island sites
- Removal of failed or old sealant
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
Details that help us quote
Whether it’s one area or a whole building, these details speed things up:
- Whether the building will be occupied during the work
- Photos of the joints, close up and from further back
- The product your specification calls for
- Any dates the work must fit around
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Construction mastic for commercial buildings in Steep
Most of the packages we price run well beyond frames: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. Splitting those between trades often leaves gaps in responsibility. We work on window and door perimeters, sanitary and kitchen joints and internal decorators’ caulk, and what we are called in for most is existing joints on a refurb that need cutting out and resealing and mastic snags holding up handover. One point of contact handles commercial sealant work in Steep from the first photos to the final walk-round, for single jobs and planned programmes alike.
Sites around smaller places like Steep can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Construction mastic in Steep: the local picture
The area within 2 miles of Steep holds a number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Central London is about 49 miles from Steep. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
For a contractor working at a hospital such as Petersfield Hospital, 1.6 miles to the south of Steep, perimeter and facade sealing is planned around patients and deliveries. New units and refits on sites such as Upper Adhurst Industrial Park (to the east of Steep) need their panel and perimeter joints sealed to the specification.
Steep is about 1 mile north of Petersfield, in Hampshire. Our applicators travel to Steep for work on mastic packages, handled exactly as we handle every other area.

Commercial clients in Steep
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Common questions from Steep clients
Do you take on work at healthcare sites like Petersfield Hospital?
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 Steep too small for you to travel to?
Not at all. Steep is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
How long does a typical visit take?
It depends on the scope, though a typical visit typically takes a day or two on a small fit-out and several weeks on a large multi-storey package. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Do your applicators hold CSCS cards?
Our applicators hold CSCS cards, and we’re CHAS accredited and a Constructionline member. We are also fully insured, with five million pounds of public liability cover.
Is colour matching possible?
It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Doing it in-house
Using site staff can make sense for a small touch-up, but larger jobs are different: 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. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Ask for joint and product checks before the package is urgent
- Flag uneven or tapered frame gaps early
- Protect sealed areas from following trades
- Release areas for mastic once other trades have finished in them
Record which products went where in the handover file. Future maintenance is easier when the products are known. We can confirm the handover information you need when we quote.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors. Getting the product and preparation right first time avoids that.
Do you need construction mastic in Steep?
Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge, so gaps outside that range need sorting by the installer first. We flag them early rather than filling them with sealant that won’t last.
Look out for the following:
- Oversized or tapered gaps around new frames
- Window and door perimeters that won’t pass inspection
- Early adhesion failures on new external joints
- Sealant knocked or painted over by other trades
For contractors at a school such as Steep Church of England Voluntary Controlled Primary School, sealing has to be finished before term starts.
Before you book anyone
- How joint depth will be controlled
- Their plan for phasing and protecting the area
- What level of public liability insurance do they hold?
- How long is the guarantee, and what does it include?
How a job runs
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For work around Steep, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- Drawings, the sealant specification and your programme come to us for pricing.
- You receive a fixed quote listing scope, products and phasing.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- We seal each plot or floor as it’s released to us.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- We close out snagging and hand over with a 12-month guarantee.
Before we start on site
- Share your working hours and any access restrictions
- Tell us what induction or permit system the site runs
- Confirm the product named in the specification
