A company's reputation isn't what it says about itself. It's what shows up in three specific places: independent review platforms a business can't edit, how the installation crew actually performs on site, and whether the warranty terms hold up years after the sale. Anyone can put "trusted" in a headline. Verifying it takes checking a handful of concrete things before you sign a contract.
Start with reviews you can't fake
A company's own testimonials page is curated by definition — of course it only shows the good ones. The reviews worth reading live on platforms the company doesn't control: Google, HomeStars, BBB, and Facebook. Look for volume as well as score. A handful of five-star reviews means little; hundreds of them, spread across multiple independent platforms, is much harder to manufacture. It's also worth reading a few of the lower-rated reviews if any exist and seeing how the company responded — a professional, non-defensive reply to a complaint tells you more about how they'll handle a problem on your own project than a wall of five-star praise ever will.
Check whether third-party accreditation actually exists
Beyond star ratings, a few concrete accreditations are worth confirming directly rather than taking a company's word for: a BBB rating (and whether the business is accredited, not just listed), any manufacturer-specific certifications, and awards from review platforms themselves, such as a HomeStars Best Of designation, which is based on a minimum review volume and score threshold rather than something a company can simply claim.
Installation quality is the part reviews sometimes miss
A five-star review usually reflects the sales experience and the finished look. It doesn't always capture whether the crew that did the physical installation was factory-trained, whether they were direct employees or a rotating cast of subcontractors, or whether they treated a genuinely different job — a full brick-to-brick replacement versus a retrofit — as the distinct methods they actually are rather than a one-size-fits-all approach. This is worth asking about directly during a quote: who is physically doing the installation, and what training do they have.
The warranty terms tell you how confident the company actually is
A reputable company backs its work with warranty terms that hold up long after the sale is closed. The strongest signal here is a lifetime transferable product warranty — one that passes to the next homeowner if you sell your house, rather than expiring or requiring the original purchaser to remain in the home. A company confident in its own installation quality has no reason to shorten or complicate that coverage.
What this looks like in practice
Applying these criteria to our own numbers: Trust Build holds a combined 4.9★ rating from 327+ verified reviews across Google, HomeStars, BBB, and Facebook, a HomeStars Best Of Award based on 145 independently verified reviews, and a BBB rating that's checkable directly on BBB's own site rather than only referenced on ours. Installation is completed by our own in-house crews rather than rotating subcontractors, and every project is backed by a lifetime transferable product warranty plus a 25-year labour warranty. Those are the specific things worth confirming about any company you're evaluating, not just this one. You can see the finished work yourself in our project gallery or read more about how we work.
A note on comparing companies directly: the criteria above apply the same way whether you're evaluating Trust Build or anyone else.
