Measuring Out-of-Square Openings
We measure each stone opening at several points and size the unit to the tightest dimension. The perimeter gap is then insulated and sealed so the surrounding mortar is left undisturbed.

Limestone village homes and new builds alike
Window and Door Installation in Rockwood and Guelph/Eramosa
GTS Windows & Doors has been installing and repairing residential and commercial windows and doors since 1986, and Rockwood is one of the Wellington County communities we cover from our Kitchener base. It sits about 40 to 45 minutes from our Bridge Street East shop, by Highway 7 and across the north end of Guelph. We are licensed, insured, WSIB covered and a SAWDAC member, and we back installations with a 20-year parts and labour warranty.
Rockwood is the main village in the Township of Guelph/Eramosa, which was formed in 1999 by merging the former Guelph and Eramosa townships. The village has two distinct characters: a 19th-century core built partly from limestone quarried at its edge, and newer subdivisions spreading along Main Street to the north and south.
Our Rockwood customers include owners of stone and frame village houses, families in newer homes, rural owners in Eden Mills, Everton and Marden, builders, and small businesses on Main Street. Each quote starts with an on-site measure, because a century-old stone opening and a new subdivision window call for very different answers. We explain the options for your house in plain terms, from custom shapes and wood repair to fibreglass frames and ENERGY STAR rated glass, and put the price in writing before any work is booked.

Rockwood Village and Surrounding Guelph/Eramosa
Rockwood grew up around the Eramosa River, which runs through the middle of the village and powered its first mills. The Rockwood Conservation Area, on former quarry and mill land, now draws more than 65,000 visitors a year to its limestone cliffs, caves, glacial potholes and the stone ruins of the Harris woollen mill.
Outside the village, the township is a patchwork of hamlets and farm country, each with its own mix of homes.
- Rockwood village: the historic Main Street core, streets along the Eramosa River, and newer neighbourhoods at the north and south ends
- Eden Mills: an 1840s mill hamlet on the Eramosa River, known for its village-wide Going Carbon Neutral project
- Everton: a compact rural community in the former Eramosa Township, with glacial potholes of its own
- Marden, Ariss and Brucedale: rural settlements in the former Guelph Township, closer to the city
Stone Houses Built From Local Limestone
Rockwood's early builders had stone at their doorstep. Colonel Henry Strange opened a lime quarry here in the 1800s, and buildings such as the 1853 Rockwood Academy on Main Street South were laid in random rubble limestone with rough-cut quoins.
Rubble stone walls are thick, which gives these houses deep window openings, wide interior sills and openings that are rarely square after well over a century of settling. Getting a new window to look right in that kind of wall takes more care than a standard insert.
Matching Shapes and Profiles
Segmental arches, tall double-hung proportions and divided lites are common in the village. Custom windows let us follow the original shape and sightlines instead of blocking down the opening.
Saving Original Wood
Some original sash and frames are worth keeping. Where rot is limited, wood window frame repair with epoxy consolidation and new sill sections can add many more years of service.
Deep Interior Returns
A new window set toward the outer face of a stone wall leaves a deep interior return. We finish the returns and sill extensions so the opening looks built in rather than patched.
Newer Homes on Rockwood's Edges
Rockwood has grown well past its stone core, with subdivisions at the north end off Wellington Road 27 near the Sacred Heart Catholic School, and further housing proposed off Harris Street in the south. The older of these subdivisions are now showing fogged sealed units, stiff sliders and drafty builder-grade entry doors.
For these homes, fiberglass windows are worth pricing, since fibreglass frames expand and contract at close to the rate of glass and hold their shape through hot summers and hard winters. A fibreglass entry door is a natural companion upgrade, with a tighter seal and better insulation than most original doors.
For custom homes and additions in the township, we also handle new window installation for builders and owner-builders. If lower energy bills are the goal, check the current window rebate programs before you order.
Permits Through Guelph/Eramosa Township
Building permits for Rockwood and the rest of the township come from the Guelph/Eramosa Building Department at the municipal office, 8348 Wellington Road 124. The township states that door and window replacements within the existing opening, where no structural members are changed, do not need a permit.
Making a new opening, or changing the size of a door or window, does require one. In a stone house that usually means a new lintel and careful masonry work, so we flag it at the measure and build the permit time into the schedule.
Heritage is worth checking too. The Rockwood Academy is designated under Part IV of the Ontario Heritage Act, and exterior changes to the heritage features of any designated property need township approval before work begins.

Rockwood Window and Door FAQs
Do you serve Eden Mills and Everton?
Yes. Both hamlets are part of Guelph/Eramosa Township and fall within our Wellington County service area, along with Marden, Ariss and the rest of the township. If you are working toward lower household energy use, we can quote triple glazing and insulated doors side by side with standard options.
Can you match the windows on a Rockwood stone house?
In most cases, yes. Custom sizes, arched tops, simulated divided lites and wood or clad-wood frames let us come close to the original proportions and sightlines. We measure every opening individually, because stone openings are rarely square.
Do I need a permit from Guelph/Eramosa?
Not for a like-for-like swap: the township exempts door and window replacements within the existing opening when no structural members change. New or resized openings need a building permit, and designated heritage properties need approval for changes to their heritage features. The Building Department at 8348 Wellington Road 124 can confirm the details for your property.
