02Photo series
The kind of work we do
The photographs come from HAP's own picture archive and are published with its permission. Each series is one object, and the description names only the work that is visible in the frame. Object names, clients, locations, years and scope are not published until the client has confirmed them.
03One package
Tell us what you need. We put the work together.
You do not need to know in advance which of our work areas a job belongs to. We look at the building and the need, and put together the package that fits.
Need more than one area? We can deliver the work on one building as a single package — one contract, one party answering for it.
04How it runs
How a project runs.
A clear path from the first meeting to a finished building. You know where the work stands and who answers for what.
We look at the site
We come to the site and see what it actually needs, so the quote rests on what we saw rather than on a guess.
We agree the work
You get a quote that spells out what the work includes and where it stops. Both sides know what the price covers.
We prepare
Materials, timing and the order of work are settled before anything starts, so the people using the building know when.
We do the work
One named person on site answers questions. Progress and anything unexpected are tracked as the work goes, not at the end.
We finish and hand over
We walk the finished work with you and put right what we find. Photographs and documents stay with the building, in the agreed scope.
05Who we work for
We build for professionals and for property owners.
We work on new build, on renovation projects and in property upkeep — from a single job to a whole building.
Construction companies
We work as a subcontractor in the agreed scope and keep to the site schedule. One named person the main contractor can get an answer from.
Housing companies
Repairs and renovation in a building that stays occupied throughout. We agree the timing and the order of work so daily life can continue.
Properties
From single repairs to larger packages. We look the building over and say plainly what is worth doing now and what can wait.

About
HAP-Rakennus OY is a construction company working in three areas: roofing and waterproofing, construction, and plastering and facades. Roofing is delivered under the Nordic Bitumen brand. The areas are a way of organising the work, not separate companies. The same company signs the contract and answers for the work, whichever area a project belongs to.
