About us

Exel Construction (S.A. FAMI)

A Belgian public limited company formed in 1993.


We are present across Belgium:
Liège, Luxembourg, Namur, Walloon Brabant and Hainaut.

The trust placed in us by our many customers and the increasing recognition of our brand have ensured that the company has grown steadily from year to year.

We limit the number of new builds to 60 per year to ensure we maintain the quality of our work and keep our operations on a scale where we can give priority to friendly customer relations and service.

We have our own tradesmen (eight teams of bricklayers) supervised by our technical department (four site managers) to provide you with a guarantee of quality at each and every stage of construction.

Specifications

Exel Construction may amend these descriptions in the interests of our customers and as technologies develop..

In addition to using quality materials, it is important to comply with the requirements of the specifications of our suppliers (tailor-made frame, drying time, etc.) to complete the building according to good engineering practice. We always complete to our time schedules, which are decided according to the size of the building.

Procedures for connections to utilities, as well as the temporary power connections required on site must be organised in due time. The detailed quantity survey takes precedence over these specifications and specifies what is included in the price.

LOW-ENERGY HOME
