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.

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.

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.

  1. 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.

  2. 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.

  3. We prepare

    Materials, timing and the order of work are settled before anything starts, so the people using the building know when.

  4. 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.

  5. 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.

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.
