Why Your Contractor Choice Is as Important as Your Design
A beautiful office partitioning design on paper can become a frustrating, costly disaster if executed by the wrong contractor. Poor workmanship in office partitions leads to crooked joints, gaps around skirting, doors that don't close properly, partitions that vibrate when walked past, and acoustic failure even in rooms that were specified for sound privacy. In Nairobi's crowded construction market, separating the genuinely capable companies from the fly-by-night operators requires knowing what to look for. This guide gives you the exact criteria and questions to use.
7 Things to Look for in a Partitioning Contractor
1. A Verifiable Portfolio
Any reputable contractor will have photographs of completed projects — ideally with client names and contacts willing to provide references. Look at the quality of the finishes in photographs: are joints tight? Are ceiling junctions straight? Is the paint even? Ask to visit a completed project in person if possible. View our completed projects here to see the standard we deliver.
2. Relevant Years of Experience
Experience in residential construction does not automatically qualify a contractor for commercial office partitioning. Ask specifically how many years the company has been installing office partition systems and what volume of commercial work they complete each year. A company completing 20+ office projects per year has the operational systems and supply chain to deliver reliably.
3. Written Warranties on Labour and Materials
A professional contractor will offer a written warranty — typically 12 months on labour defects and will pass through manufacturer warranties on materials. If a contractor hesitates to provide this in writing, regard it as a significant red flag.
4. Licensed and Registered Workers
Workers on your premises should be formally employed or contracted, with public liability insurance in place. Ask to see the contractor's insurance certificate before work commences. This protects you if an accident occurs on your site during the fitout.
5. A Written, Itemised Quotation
Oral estimates are worthless. Insist on a written quotation that itemises quantities, unit rates, material specifications, and payment terms. A good quotation will describe the partition system, board specification, door hardware, paint type, and exclusions clearly. This document is your protection if disputes arise.
6. Dedicated Project Management
For projects above KES 500,000, you should have a dedicated project manager or site supervisor who is your single point of contact. Contractors who send anonymous teams to site without a named supervisor typically deliver inconsistent results.
7. After-Sales Service and Snagging Resolution
No construction project is perfect on the day of handover. The difference between professional and amateur contractors is their response to a snagging list. Reputable companies return within an agreed timeframe to rectify items at no additional charge. Ask about their snagging process during the tender stage.
Questions to Ask Before Appointing a Contractor
- Can you provide three references from similar-scale commercial projects completed in the last 12 months?
- Who will be the named project supervisor on my site?
- What is your programme — start date and estimated completion?
- What partition system brands do you work with?
- How do you handle variations to the original scope?
- What does your warranty cover, and for how long?
- Do you have public liability insurance? Can you share the certificate?
Red Flags to Avoid
- No written quotation. Any contractor unwilling to put their price in writing is not a professional.
- No site visit before quoting. Accurate quotations require a physical measurement of the space. Quotes issued over the phone without a site visit will have errors — usually resolved at your expense through variations.
- Unusually low prices. In Nairobi's partitioning market, a price 30%+ below the median for the same specification is a signal that something has been excluded — usually material quality, proper acoustic treatment, or door hardware.
- Demand for large upfront payments. A standard payment structure is 30–40% mobilisation, milestone payments during construction, and 10–15% retention on completion. Requests for 70–100% upfront are a serious risk.
- Unregistered subcontractors. If a contractor intends to subcontract your work to an informal gang, your risk exposure increases significantly.
