USPTO Trademark Classes Blog Series: Class 37 – Construction and Repair Services

Welcome back to our USPTO Trademark Classes Blog Series, where we break down each trademark class to help businesses properly categorize and protect their brands.

In this installment, we’re covering Trademark Class 37, which includes construction, building maintenance, and repair services. If your business operates in the trades—whether that’s general contracting, plumbing, electrical work, or property maintenance—this class may be the right fit for your trademark.

If you’ve ever asked, “Can I trademark my construction company name?” or “Does my HVAC repair business fall under Class 37?”, this guide will help clarify whether this classification is appropriate for your brand.

What is Trademark Class 37?

Trademark Class 37 includes services related to building, installing, maintaining, and repairing structures, machinery, and infrastructure. This class is used by a wide range of professionals and businesses in the construction, property maintenance, and home services industries.

Some examples of services that might fall under Trademark Class 37 include:

• General contracting and building construction

• Electrical, HVAC, and plumbing services

• Roofing, flooring, painting, and drywall installation

• Renovation and remodeling services

• Appliance and equipment installation or repair

• Property maintenance and landscaping

• Vehicle and machinery repair services

If your business builds, installs, fixes, or maintains physical property or equipment, Trademark Class 37 is likely the correct classification.

Why Trademark Class 37 Matters for Your Business

Registering a trademark under Class 37 helps protect your brand in the construction and trades industries, where strong local name recognition is often key. Here’s why filing in this class might be important:

1. Prevents brand confusion – Construction and repair businesses often operate under similar-sounding names. A registered trademark gives your brand legal priority.

2. Builds customer trust and reputation – When customers see a registered trademark, it reinforces your brand as established and legitimate.

3. Protects your business name as you grow – Whether you’re expanding into new service areas or franchising your brand, a trademark supports consistent branding.

4. Reduces legal risk – If someone else begins operating under a similar name in your field, your trademark gives you the right to take action.

Examples of Trademarks in Class 37

Many construction companies and service providers have registered trademarks in Class 37. Some examples include:

• Mr. Rooter® – Covers plumbing installation and repair services

• Handyman Connection® – Registered for home repair and remodeling services

• Mister Sparky® – Trademarks for electrical installation and maintenance services

These companies use trademarks to protect logos, slogans, and business names that customers recognize and trust.

Do You Need a Trademark Search Before Filing in Class 37?

Yes. A comprehensive trademark search is especially important in Class 37 because many local and regional service providers may use similar names. Without a search, you could unknowingly file a trademark application that conflicts with an existing brand.

At Brand Diplomacy, we offer full trademark clearance services to help you avoid roadblocks and assess whether your brand name is available and protectable.

How to Determine if Class 37 is Right for Your Trademark

If you’re unsure whether Trademark Class 37 is the correct category for your business, consider the following:

1. Does your business involve physical repair, installation, or construction work?

   • If yes, Class 37 is likely appropriate.

2. Are your services focused on homes, buildings, vehicles, or mechanical systems?

   • Most on-site services for physical structures or machines fall under this class.

3. Do you also offer design, consultation, or supply sales?

   • Those might fall under different classes. For example:

     • Architectural design services may belong in Class 42

     • Retail of building materials might fall under Class 35

     • Home design consulting or staging could also fall under Class 42

   
   

If your business crosses over into other areas, you may need to file in multiple classes to ensure complete brand protection.
