How to Vet a Construction Contractor in Kenya: What to Ask Before You Sign
Choosing the right contractor can make the difference between a smooth construction project and months of delays, unexpected costs and poor workmanship. Whether you are building a home in Nairobi, renovating a commercial property in Westlands, developing apartments in Ruiru, or undertaking a larger project elsewhere in Kenya, knowing how to vet a construction contractor in Kenya is essential before signing a contract.
A professional contractor should be able to demonstrate proper registration, relevant experience, qualified teams, clear pricing and a realistic project schedule.
Here is a practical checklist to use before hiring your next construction contractor.
1. Can They Show You Previous Projects?
A contractor’s portfolio tells you considerably more than a sales pitch.
Ask to see completed projects similar to yours. If you’re building a residential house, look for previous homes. If you’re developing apartments, offices, a hotel or commercial property, ask for projects in the same category.
Don’t just look at photographs. Where possible, ask for references from previous clients.
Ask:
- How many similar projects have you completed?
- Can I visit one of your completed projects?
- Can I speak to a previous client?
- Who supervised the project?
SUIMAS Interiors, for example, combines construction with interior design, allowing clients to work with one coordinated team from construction through to finishing and furnishing.
2. Who Will Actually Manage the Project?
The person who gives you the quotation may not be the person running your site.
Find out who will be responsible for daily site management, quality control, subcontractors, materials and communication.
Ask whether the project will have a dedicated site supervisor and how frequently you will receive progress updates.
This becomes particularly important for larger projects where several trades must work together.
3. What Exactly Is Included in the Quotation?
Never compare contractors based solely on the final figure.
One contractor may quote KES 8 million while another quotes KES 6 million, but the cheaper quotation may exclude flooring, painting, plumbing fixtures, kitchen cabinets, electrical fittings or external works.
Request an itemised quotation or Bill of Quantities where applicable.
Your quotation should clearly identify:
- Materials and specifications
- Labour
- Structural works
- Plumbing
- Electrical works
- Roofing
- Flooring
- Painting
- Doors and windows
- Interior finishes
- External works
- Professional fees where applicable
- Taxes and other applicable costs
For projects requiring formal NCA registration, the Authority lists an approved architectural and structural drawing set, consultant details and a signed BOQ summary among project-registration requirements.
4. How Are Changes and Additional Costs Handled?
Construction projects sometimes change. You may decide to upgrade tiles, add another room or modify the kitchen layout.
The problem occurs when changes are made verbally and the additional costs only appear at the end.
Your contract should explain how variations are requested, priced and approved.
Ideally, additional work should be documented and approved before it is undertaken.
5. Do They Handle Interior Finishing Too?
Construction doesn’t end when the roof goes on.
For many clients, the final appearance of the property is just as important as the structure. Ask whether your contractor can coordinate finishing works or whether you will need to find separate companies for every stage.
SUIMAS combines construction with interior design, renovation and finishing, allowing clients to coordinate construction and interiors through one project team.
This can include Residential House Construction Services, Building and Construction Services, flooring, painting, gypsum, kitchens, office fit-outs and interior design.
For clients planning a complete transformation, our previous guide on Construction and Interior Design Company in Kenya explains why combining the two services can reduce coordination problems.
6. Check Their Approach to Quality and Safety
Ask how the contractor controls workmanship and site safety.
A professional contractor should have systems for supervising workers, checking materials and addressing defects.
The NCA also has an accreditation framework for construction workers and site supervisors, reinforcing the importance of properly skilled personnel on construction projects.
