Hardscaping contractorin Woburn, MA

What holds a paver surface together through freeze and thaw, how to pick a material, and what to ask any hardscaping contractor before you sign.

Why the base decides whether a patio stays flat

In Massachusetts the ground freezes and thaws many times each winter. Water that sits in the soil under a patio expands when it freezes and lifts whatever is on top, then lets it drop unevenly in spring. That is why a patio, walkway or driveway that looked perfect in June can be rocking and tripping people by March.

The fix is underneath the pavers, where nobody looks once the job is done:

• Dig out the soft stuff. Topsoil and organic material hold water and compress, so they come out. A driveway gets a deeper dig than a patio because it carries cars.
• Build a gravel base in layers. Processed gravel is spread and compacted a few inches at a time. One thick pass with a plate compactor leaves the bottom loose.
• Pitch it away from the house. Every surface gets a slight slope so rain runs off toward the lawn or a drain, never toward the foundation.
• Lock the edges. An edge restraint keeps the field of pavers from creeping outward, which is where most gaps and sunken borders start.
• Fill the joints. Polymeric sand swept into the joints sets up, holds the pavers together and slows down weeds and ants.

When two quotes for the same patio are far apart, the difference is usually here. Ask every contractor how deep they dig and how they compact.

Pavers, brick, natural stone or concrete

We install all four, so we can tell you honestly where each one fits.

• Concrete pavers. The most common choice for patios, walkways and driveways here. We are a Unilock and Techo-Bloc installer and also set Belgard and Pavestone. Unilock Brussels Block, with its tumbled, old-world look, is the one our customers pick most for walkways, and Beacon Hill Flagstone gives a stone look at paver strength.
• Brick. Clay brick pavers suit older colonials and capes and look right next to a brick front step. We build brick patios and walkways as well as paver ones.
• Natural stone. Bluestone, granite and fieldstone for patios, step treads and walls. Granite steps and a fieldstone wall are what we used on a pool area in North Reading.
• Poured concrete. For pads, walkways and driveway aprons where a paver isn't the right call, we pour 4000 PSI concrete and finish it smooth, brushed or with a decorative texture.

Pavers have one advantage worth knowing before you choose. A poured slab that cracks has to be cut out and patched. A paver that settles or gets stained can be lifted out and reset or swapped, and the repair disappears.

Driveway pavers, extensions and aprons

A driveway is built differently from a patio because it carries cars and a plow: a deeper dig, a thicker base and a paver rated for vehicles. Widening strips, borders and granite aprons are options when the old driveway doesn't need to come out completely. Our driveway pavers page covers how we build them, from the base to plowing and the street apron.

Walkways, curves and steps on a slope

Front walks and the steps up to the door take daily traffic, shoveling and salt, so they need a solid base, clean edges and even risers. Our walkways and stairs page covers layout, materials and building steps to code; repairs to existing brick and stone steps are on our masonry services page.

Building a patio on sloping ground

A sloped yard rarely rules out a patio: the base takes up a gentle grade, and a steeper one is handled with steps or two levels. Our patio design and installation page explains how we plan patios, slopes and seat walls.

Fire pits and seat walls

A fire pit and a seat wall are easiest to plan with the patio, so the base, the layout and the materials work together. Our outdoor fire pits page covers shapes, wood or gas, and how we build them to handle heat and frost.

How a hardscaping price is decided

Every yard is different, so we price each job after seeing it. What moves the number is explained in our paver patio cost guide and on the driveway pavers page. The visit and the estimate are free, and you get a price before any work starts.

Permits, Dig Safe and other rules

A patio or walkway at ground level usually doesn't need a building permit, but tall walls, driveway changes at the street and work close to wetlands can need approval from your town's building department, DPW or conservation commission. Gas, electric and phone lines are marked through Dig Safe, which Massachusetts requires at least 72 hours before any excavation.

How to choose a hardscaping contractor

• Ask how deep they excavate, what base material they use and how they compact it.
• Ask what holds the edges and what goes in the joints.
• Get the price in writing, with the material named.
• Ask to see work that is several years old, not only last month's photos. Base problems show up after a few winters.
• Check that they are insured and read their reviews. We are fully insured, our work is guaranteed, and we hold a 4.6 rating from 41 Google reviews.
