Stone retaining wall by Dias Souza Construction
Est. 2017 · Lowell, MA
Our Story

Eighteen years of stone,
brick, and concrete.

Dias Souza Construction was founded in 2017 by Nilson de Souza, but the craft started long before the company name did. Nilson has been laying stone, setting pavers, and pouring concrete across Greater Boston for over 18 years — long enough to remember every wall he's built, and every customer he's built it for.

Today, Nilson leads a team of 4–6 skilled craftsmen serving homeowners across Massachusetts, southern New Hampshire, and Rhode Island. From small front-walkways to large retaining walls, every project gets the same care — because the goal isn't to finish fast. It's to build something the next generation will still admire.

"Preço justo e trabalhamos com honestidade e seriedade, sempre focados em agradar os clientes." — Nilson de Souza

Translation: Fair pricing, and we work with honesty and seriousness — always focused on satisfying our customers. It's how the company runs. It's how every job gets done.

How We Work

The way we run
every project.

Six principles that hold whether the job is a single walkway or a thousand-square-foot patio. They're how we earn the next call — from the same client, or their neighbor.

01
Free, Honest Estimates

No high-pressure sales. We come out, measure the job, listen to what you want, and give you a straight number.

02
Fully Insured

Liability and workers' comp on every job. Your property and our crew are both protected — always.

03
Local Team

Based in Lowell, with 4–6 craftsmen who've worked together for years. No subcontracted strangers.

04
Built to Last

Proper drainage, frost-line footings, mechanically compacted base. The work outlasts the season — and the next ten.

05
On Time, On Budget

We say what we'll do, then do it. If something changes during the job, you'll know before we move dirt.

06
Clean Worksite

We pick up after ourselves every day. When we leave the site, you can use it.

Our Promise

"Every project is built to endure — from the foundation up. The work we do today is still standing in 30 years."
