A guide to Stamford's 22 gutters and siding contractors: what the work involves, what separates a solid installer from a risky one, and how to compare options.
Gutters and siding get lumped together because the same crews often handle both: they're the parts of a house that manage water and weather at the exterior, and both take a beating from Stamford's mix of coastal humidity, winter freeze-thaw, and heavy fall leaf drop off oak and maple canopy in neighborhoods like Springdale and North Stamford. Gutter work covers installation, resizing, seamless aluminum runs, leaf guards, and repair after ice dams or storm damage. Siding work covers vinyl, fiber cement (like James Hardie), and wood repair or full replacement, plus the flashing and trim details that keep water from getting behind the material in the first place.
With 22 companies serving the area, quality varies more than price does. Look for contractors who measure and fabricate seamless gutters on site rather than using pre-cut sections with more joints to fail, who spec the right hanger spacing and downspout count for your roof's water volume, and who carry manufacturer certifications if you're installing fiber cement siding, since that affects warranty coverage. Ask how they handle flashing at windows, corners, and roof intersections, because that's where most water intrusion actually starts.
Our scores weigh licensing, insurance, verified reviews, response time, and how consistently a company follows through on warranty work, not just star ratings. See the full breakdown in our methodology, or skip straight to the ranked guide to Stamford's best gutter services for our top picks.

Arsim and his crew earn consistent praise for finishing projects on time and on budget, with clear communication and professional workmanship throughout. Reviewers highlight the team's responsiveness to questions, clean work practices, and ability to handle complex repairs and replacements across decking, bathrooms, exterior walls, and siding with minimal disruption to homeowners.
Reviewers consistently experience fast, attentive service from a team led by Santos and Roger. Work spans slate leak repairs, full replacements, flashing and chimney work, with crews sending aerial photos during the job and leaving sites immaculate. One reviewer with a longstanding porch leak praised their proactive discovery of a second issue and one-day fix after heavy rain. Materials arrive promptly (a week noted), and the outfit handles permitting and inspections in-house. Pricing lands as fair and competitive. Follow-up visits at no cost have resolved lingering concerns. All 136 reviews rate five stars, with no one-star complaints recorded.
Most clients praise Gunner for quick turnarounds, daily cleanup, and project managers who listen and follow through during active work. Andrew, Joe, Zack, Jesse, and Chris earned specific mention for transparency and responsiveness. Siding and roof installations typically meet or exceed expectations, with crews returning to fix details after final payment. Friction arises after the job ends. Several reviewers report weeks or months of unresponsiveness to warranty leak claims, property damage claims, and post-installation corrections. A few describe aggressive pre-sale follow-up and felt rushed into scheduling. Subcontractors sometimes lack on-site Gunner oversight, creating communication gaps when issues surface during work.
Evelyn and Alex's team delivers roof work efficiently and professionally, consistently meeting timelines. Customers praise clear communication, competitive pricing, thorough cleanup, and quality installation. Strong follow-up service keeps repeat clients returning.
Signature Exteriors earns strong praise for responsive service, skilled installation work, and meticulous site cleanup across roof and siding projects. One complaint documented trespassing and fence damage without communication; otherwise 94% five-star ratings reflect consistent professional execution from initial estimate through final walkthrough.

Customers repeatedly mention carpentry repairs, power washing, and a two-year paint warranty, often paired with roof or gutter work. Pricing comes across as fair and competitive across multiple reviews. The team cleans up daily, replaces rotted wood without upsell, and handles unexpected problems with grace. No negative patterns emerged across 19 five-star reviews.
All 13 reviews award five stars. Customers consistently highlight Kevin and his team's responsiveness, attention to detail, and ability to finish jobs on schedule or early.

Jobsites remain clean, communication stays transparent throughout, and reviewers note the team takes evident pride in craftsmanship and material quality.
Twenty-five reviews paint QNK Roofing as precise and reliable: crews diagnose leaks correctly rather than patch them, arrive on schedule, finish ahead of time, and leave properties spotless. Named techs Patricio and Fernando earn specific praise for attention to detail on specialty materials like cedar and slate. One older complaint flagged a worker who misidentified a chimney issue and overestimated costs; recent reviews show consistent responsiveness and fair pricing.
Every review praises Dillon, the owner, for his knowledge, responsiveness, and integrity. He diagnoses complex problems carefully, arrives quickly for emergencies, and finishes work with meticulous care-including personal follow-up cleanup. Customers return repeatedly and report beating other quotes while maintaining premium workmanship.
Reviewers consistently report arriving on time, completing work to spec, and staying in touch throughout the job. Klevis and his team (including Gendi) earn praise for handling detail work carefully, addressing problems creatively, and treating homes with respect. The standout feature is repeat business: customers return for multiple projects, citing dependability and consistency as rare finds in contracting.
One Stop 360 earns strong marks for straightforward jobs like decks, fencing, and roof replacements, where Herson and his crew often deliver on time, keep sites clean, and listen to customers. Owner Herson is frequently mentioned as personable and communicative. However, two detailed negative reviews flag serious problems on larger, more complex projects: poor window installation quality control, subcontractor hiring decisions, and a pattern of unresponsiveness after payment. The gap between five-star and one-star experiences suggests this team performs well within their comfort zone but stumbles when projects involve detailed finishes or coordination across multiple trades. Customers report fair pricing on straightforward work, though one reviewer noted scope creep and cost adjustments mid-project. The company handles bathrooms, decks, fencing, and roof work, but the window and roofing experience described raises questions about their ability to manage complex installs to spec.
All five-star reviews across eight ratings. Samuel and his crew handle roof repairs and replacements with speed and care. Customers praise competitive estimates, rapid completion, clean work, and professional demeanor. Limited review detail, but the pattern is consistent satisfaction.
